Can't select above 320 x 240 in VDub??

[mb571]

Hey pals. I am trying to capture with virtual dub but it will not let me select anything greater than 320 x 240. In PowerVcrII I have no problem with 640 x 480. I am using an ATI tv Wonder. Any ideas??

Another question: Can you selcet to capture to avi with power vcrII or just mpeg? Can't figure out how to go avi with huufy.

Sounds like maybe you have the viewing mode set to Overlay instead of Preview? Overlay mode only goes up to 240 lines of vertical resolution.

I tried your tip. Selected, Video, then checked preview but I still get the same error when selecting 640 x 480

ERROR 418: Unsupported video format.

ATI Tv Wonder use it's own (limited) drivers. PowerVCR use WDM, and Virtualdub use VFW, so I'm not sure what drivers you're using. You might be using a WDM to VFW wrapper, that has some limitations. Anyway, the problem is the drivers. Get some generic drivers, or get some new WDM drivers. But, you cannot use Virtualdub with WDM, you will have to swirct to VirtualVCR. Or do a search, there are tricks to get the ATI Wonder to capture in 640x480 with the wrapper software.

The ATI tv wonder is a bt8x8 card. Try the drivers off sourceforge. I use VirtualdubVCR with it and it works excellent.

Okay I have the generic driver from:
http://btwincap.sourceforge.net/
I also loaded VirtualVCR. I have lost my audio now so I'll have to look into that. Another problem is in the TV Tuner section of VirtualVCR it only allows PAL-B or Secam, but not NTSC????
I am also not sure the tv tuner is set up right. It is out by 1 channel compared to my tv. Also, in powerVCRII, there is alot of distortion for about 3 seconds after changing channels.
All the help is being appreciated guys.

Okay I removed and re-installed the drivers and got the sound working again. But the tv tuner is still out by one channel. It may be due to me selecting Auto Detect tuner in the driver setup as I do not know the specific tuner that is in an ATI TV Wonder ????

Not sure about the TV tuner. Try to stick to s-video as much as possible, quality will be much better like that.

Things are very twitchy over here again. Audio is missing.

A little more progress. Pulled the card out to see that it is a Philips tuner mounted on the board. Captured a clip at 640 x 480 with Huffyuv but it appears to have a bit of audio de-sync.
