Windows XP and BTwincap Help!

[edg]

What the heck happened?

I have been running great using a Win-TV-GO board, BTwincap drivers, VirtualDub, TMPgenc, DVDdecrypter, DVD shrink, IMGtool and Windows ME. Captures have been good, always in sync, and good quality transfers from my video camera to DVDs, with the final videos at 740x480 and 29.97fps.

I got tired of wierd lockup problems with ME and wanted to add a larger harddrive with Windows XP to eliminate the instability and eliminate smaller file size restrictions with ME.

Now I have XP installed with the original WIN-TV drivers. As before, I can't get above 320x240. I tried to use the BTwincap drivers to get back to 740x480 but all heck breaks loose. The drivers don't seem to load correctly and I also lose use of the original programs using the originally working drivers. So now nothing works, AMCAP, VirtualVCR, the WIN-TV program, nothing.

I have reformated the hard drive again and started over, but same thing.

From everything I have read on the forums, BTwincap works great with XP.

HELP. What am I doing wrong?

[chris1379]

Just wondering if you ever got it to work. I also hava the same problem.

[edg]

No, I never got it to work. I contacted Eduardo José Tagle (current owner of the Btwincap website) in September. He said then he did not have time to fix the driver and update the installer. Guess it's a dead dog now. I get the feeling it's not going to get updated.

Maybe I'll resend the email to see if I get any new response.

[chris1379]

Thanks for getting back to me. I guess I'll go shopping for something better.

I am using the lastest BTWINCAP drivers with BT848/878 cards in 2 PC's here. They work without a problem with Windows XP (SP1 /SP2).
Virtualdub, AMCAP, Iuvcr and others work ok for me in full PAL (704/720x576 YUY2) resolution.
The only thing what does not work correctly is the overlay function. But that's no problem for me.
I am mainly using it in combination with AVI_io.

[edg]

I know a lot of people have no problems and others do with XP.

Here's the original post and reply about the install problem. Evidently he has know about the exact problem.

In fact, ai have a not released yet driver version that fixes exactly that problem... The only thing stopping me from releasing it is that i don't have enough time to update the website and create the installer...

Subject: BTWINCAP installation problem


Hello Eduardo,

I previously used the BTWINCAP driver with Windows ME, and captured and burned with various programs, no problems. The drivers worked great and I was capturing at 720x480 with my Win-TV-Go card.

I changed my system to Windows XP to eliminate the instability of Windows ME, but now have the problem that I cannot get the BTWINCAP driver to load. I have tried all different ways of getting it to complete running, but it seems to hang and reboots at the end of the installation.

I have no idea why. From the different forums I have read it seems that it works great with XP on some machines but others have problems loading it also.

Upon some different forum suggestions, I tried installing with virus program off and same problem, it rebooted and didn't load.

I also tried installing in safe mode and it wouldn't restart properly from safe mode. It told me there was a problem and I would have to restore from last good startup.

I am installing BTWINCAP per the instructions (not deleting the existing drivers) and trying to load it over the original card driver. I have also tried to load BTWINCAP alone, without installing the WIN-TV-GO driver first, and that wouldn't work either.

I have read some posts that said in some cases, the registry(?) may be screwed up, but I don't know how to do any corrections here.

I have tried installing the driver and restored XP so many times, I have lost count. I have been trying to load this for 3 months already.

Any help would be greatly appreciated. I am at the end of my rope with it.

Thanks,
Ed Good

Well, I have since gone back to the Hauppauge driver (yuck) and am using AMCAP or VirtualVCR to capture at 720x480, but have plenty of audio sync problems where I had none when capturing with VirtualDub and the BTWINCAP driver at 720x480.

Maybe someday the BTWINCAP Gods will shine on my setup again.

[chris1379]

That's odd. I tried Amcap and it wouldn't let me above 240 lines either. There has to be something I'm missing. I know it takes 2 DMA channels to capture both fields so I'm going to see if maybe I only have one DMA channel available.

[chris1379]

I just did a successful capture at 720x480 with VirtualDubVCR+sync and the BTWincap drivers. I apparently had not uninstalled the old drivers. I had to go to device manager and uninstall the devices, reboot, uninstall BTWincap, reboot, install BTWincap, and reboot. Immediately before you install BTWincap, make sure you have 2 yellow exclamation points listed under Other Hardware. I also had to wait through several minutes of unresponsiveness in VirtualDub while changing drivers, source, etc. I also found out a while back that I had trouble capturing to an SATA drive. I have to use an EIDE which will work for me. I'll try a DVD conversion later.

[edg]

Did you install the Hauppauge driver first or went straight with the BTWINCAP driver only? Looks like it might be worth a try using your uninstall/install sequence. I have tried so many different sequences I don't remember what I used anymore.

Also, what is VirtualDubVCR+sync? I don't see this particular tool in the list.

[chris1379]

I installed the Hauppauge driver when I re-installed Windows. I uninstalled that driver from the device manager. I also had to uninstall the BTWincap with the uninstall utility provided. When Windows detects new hardware, cancel the wizzard. Look in the device manager and make sure there are 2 yellow exclamation points under other devices. Then install BTWincap. VirtualDubVCR+sync is just VirtualDub with a timer and modified sync routine. I have since tried VirtualDub and played a finished DVD on the TV.

CHRIS1379:

I am still at the same problem, the computer reboots during the autoinstall of BTWINCAP and doesn't complete the driver install for the WDM capture driver.

I even tried, again several times, the hand install using the bt848.sys file.

I don't get it. During the hand install I edit the five "$" locations in the BT848.inf file per instructions and then manually install the driver during the Wizard install by selecting the BT848.sys file.

Computer reboots during install and starts up with the desktop error window and no driver loaded.

After 4 hours of trying to reload this monster again, I guess it's back to the Hauppauge drivers.

[edg]

I have just spent another 2 hours on this. I booted and installed in Safe Mode and the install program would now run to completion. The device manager shows it as installed as the Conexant driver loaded, BUT, the computer locks up and reboots.

If the driver is enabled, the computer will not start up except in safe mode. If the driver is enabled, the PC shuts down and reboots.

There must be some kind of conflict but I have no idea where to begin. It is the lastest BTWINCAP driver 5.3.8.

The device manager lists the following files under driver details:
system32\drivers\bt848.sys
system32\drivers\stream.sys
system32\iyuv-32.dll
system32\msh263.drv
system32\msyuv.dll
system32\tsbyuv.dll
system\32\vfwwdm32.dll

Do these look like the same files listed under your system? I have no idea where to go with this next.

[chris1379]

Sorry if I dug up something bad. It sounds like you have some type of conflict. Can you set the resources on PCI slots manually? If not, you could try a different PCI slot. I have more files than that for my driver details. I wish I had an easy way to copy/paste the list. Here's what I have:

system32\drivers\bt848.sys
system32\drivers\ks.sys
system32\drivers\stream.sys
system32\iyuv_32.dll
system32\ksproxy.as
system32\kstvtune.ax
system32\ksuser.dll
system32\kswdmcap.ax
system32\ksxbar.ax
system32\msh263.drv
system32\msyuv.dll
system32\tsbyuv.dll
system\32\vfwwdm32.dll
system32\vidcap.ax

This may or may not be relevant but I have been having a similar problem and I've been slowly working on a theory. Some back data...

I have used the BTwincap drivers in both WIN98 and WINXP flawlessly until very recently. I have re-installed several times and even resorted to installing my card's native drivers (ATI TVWONDER VE) to get this to work and NOTHING helps. (on WIN98 machine... no longer running XP)

My brother uses the same capture card as I do but runs XP and with the latest drivers from ATI. HE suddenly cannot capture worth a damn either.

I have recently acquired a dvd writer and it came with an OEM version of Nero 6.x. which comes with NeroVision express... which includes a video capturing program. My brother has also recently installed Nero 6.x and began having trouble.

I can't prove that Nero 6 is the problem since uninstalling it hasn't helped. I have noticed that my VFW wrapper has been replaced by "something else" but cannot get any company info from the file. An "MS video device" or something similar is now listed in my system properties. This entry is new and I haven't installed any new hardware. I've been digging DEEP into the workings of windows and my drivers and my theory is something like this...

I'm wondering if video capture works through a "layer" similar to the ASPI layer that most (all?) cd-writers have to work through. If so, I believe that this "layer" has been updated/replaced by either Nero or some other software and will not revert to its previous state.

I'm not interested in reformatting and re-installing everything to find out. If I had a spare HDD around I might try a new install but I just don't have time. I only share the theory since it sounds like you're having similar problems. My theory could be wrong and I might be an idot, but the only thing my system has in common with my brother's is the capture card and the NERO program, but we both have the EXACT SAME PROBLEM, which sounds just like yours.

I can now only capture using AMCAP and only at 240 lines with lousy quality and out of synch audio. I previously captured as high as 720x480 with perfect audio synch using virtualdub. Now virtualdub can't even see my capture card.

I posted about this myself before and got the usual "update to latest drivers" responses, which can't be done with WIN98 and ATIs newest drivers. I've pretty much been out of business for months now. It's frustrating!

Regards,
Nitemare

[chris1379]

I have Nero 6 also but I'm running XP. My problem seems to be solved. If I changed anything in Nero, I don't know it. I wish someone could find the answer because I feel like my capturing abilities could just go away again at any time.

[edg]

Well I have again tried moving the card to different pci slots and reinstalling BTWINCAP and nothing. Still hangs and reboots during the BT848.sys install.

I still don't understand why it worked flawlessly with WIN-ME and won't install with WIN-XP Pro. When I originally installed WIN-XP on a new HD, I kept the WIN-ME on another. I remember swapping the HDs as bootdrives to make sure it had to be a problem with WIN-XP and not the hardware. It was and still is.

I do remember installing the trial version of Nero a while back, both with ME and XP. I did have some problems with the PC after that. I remember removing Nero when it expired but wierd things were going on with my CD and some other programs, but I don't exactly remember it all.

I wish they would get back to fixing/updating the BTWINCAP installer.

Oh well, back to the Hauppauge driver.
