ATI TV Wonder VCD problems (this is no ordinary problem!)

[xyphan]

As you can see from the subject line, I have an ATI TV Wonder. My system is as follows...

AMD T-Bird 1200 MHz
384 MB SDRAM (PC-133)
30 GB HD (7200 RPM)
MSI K7T Pro2-A (KT-133 chipset) (2.9 BIOS and version 32 chipset drivers)

NVIDIA GeForce2 GTS
Nero 5.x
ATI MMC 7.1

Now my problem is this: I record using a custom preset to real-time MPEG (using the registry tool - 1150000). I don't use visual masking, and I have the motion estimation at 100, but the search ranges are at 32 and 16. I capture a movie and it encodes just fine, there's no sync problems or anything. I split it with iFilm Edit using the VCD option checked. The files still are at perfect sync. Now, here's the confusing part. I've tried to burn it to a VCD from this point, but after playing the VCD for about 15 min, the video is out of sync on the DVD-Player (Philips DVD711)! So I've tried demuxing it with TMPGenc (i), and then remuxing it with the philips toolkit MUX program. I play the file on my computer, and it goes out of sync after about 20 to 25 min (the other didn't go out of sync on the computer). So, even though it is out of sync I burn it to VCD and it went out of sync. Anyone know why this happens? I've even tried demuxing with bbdmux, and remuxing with philips and avi2mpg. Still, the same problem! There is one thing I should tell you, my computer is loaded, so I have no choice but to share an IRQ with something else (I don't think that's the problem though). I've tried using virtual dub to capture using the VFW wrapper, but the file sizes just got too big, and it crashed a lot too. ATI doesn't seem to have anything about this problem and I haven't found it in this forum either. Please help me! This is getting quite annoying!

thanks for your time!

Hmm, first off, test out the disc on another dvd player if possible. Secondly, were you doing something on the computer while u were recording? I have this problem with one of the captures that I made. I wasn't doing anything but my screensaver (the search for cancer cure one) came on and it stopped the recording a bit. I played the capture file and it plays fine on my computer, but when I went to try and edit it (to cut commercials) with TMPGenc, parts of the capture were out of sync. I went back and realized the part that got interrupted by the screensaver was causing it to be out of sync. My point is, when you played the file on your computer, it didn't go out of sync because it was reading additional information about the timecode to compensate. The DVD player doesn't do that so it eventually went out of sync. The same happened to me on the computer because the cropped files didn't have the additional information need for the software to compensate. Well, that's my guess anyway, I hope someone with more technical knowledge about this can explain the situation better.

That's the weird thing, when I record something on my computer I go off and do something else and I make sure the screen saver is off because I've had that kind of a problem before. I have tried another DVD player and it does the same thing. The only way I can get the dvd player to make it play correctly is if I rewind, then play it, and the AVsync is back to normal, but it eventually goes off again. I have tried re-encoding the whole movie (which takes too long!) and it worked just fine. But hey, I'm only human, and I don't wanna wait!

AMD T-Bird(c) 1200 mHz
512 DDR Ram
45gig HD @7.2 rpm
MSI KT266 pro
ATI 32mb DDR Radeon A-I-W
Nero 5.x
ATI MCC 7.1

I can't say whether the problem exist on any other system when it comes to the VFW/MCC 7.1 drivers. With the old BrookTree drivers (& ATI TV Wonder) my 3 other system would lockup. I began to messure how well I had optimized a system by how long I could get it to operate & time the lockup.
With the purchase of my Radeon A-I-W (purchased to receive larger recording appertures; something other then 352x240), and switch to VFW drivers the lockup dissapeared. However, minute loses in frame rates surfaced (<1%). It's my belief that these loses always add up to out-of-sync errors.
The closes I've come to controlling the problem is by installing Memory Managers. Currently I'm using "RAM Idle".
Before any recording I reclaim memory; during commercials I close the TV and reclaim, and pretty much avoid losing anything in the recording process. I've begun to realize that these drivers are accessed by all of the video processing software so I try to clear memory before a video process.

Hope it Helps

I hpe this might help i had a problem almost the same. When I burn it I got cracks in the sound I found the problem it was the Ram in my system make sure. Two sticks of ram did not like each other. Second My freind has a PHILIPS DVD player its alway out of sync with the sound. The Philips seemd to like Memorex. I also found the old PNY to work on the Philips very good but they changed there Cdr's to light green. Make another post asking whats cdr's work with Sony DVD's player's and Philips.

Hey, thanks everyone for your help! I've tried the RAM Idle program, and it works great! Before I actually set everything on it, I was curious just to see what my RAM was when recording. I launched up MMC 7.1 and started recording. The RAM went from 288 all the way down to 66 MB in less than 2 minutes (now I wouldn't think that's normal). So I tweaked the RAM settings and now it doesn't go below 192 MB. Now, I've moved on to better ways of recording. What I'm now doing is, instead of recording at 1.14 Mbits/s, I'm recording at 5 Mbits/s and then re-encoding with TMPGenc. I figure, if the sound's going to be fixed anyway, why not get better image quality to! The thing that sucks is that I had to do some math to figure out the bitrates for video so I wouldn't hit the 4 GB limit of FAT32. I've gone all the way up to 3 hours (2.6 Mbps). Thanks again!
