Hello...

I have been trying to capture video from a vcr to my computer using a sony dcr-trv27 minidv and analog to digital passthrough via firewire. My computer specs are as follows:

Athlon 1.4
Abit kg7 (chipset= AMD761/VIA 686B)
512 ddr pc2100
soundblaster live
ati aiw 128
adaptec firewire card
two 40 gig 7200rpm hardrives (one master/one slave)
pioneer dvd as master, hp 200i dvd+r/+rw slave

I am using current drivers for hardware as well as via chipset drivers v4.38. Newer chipset drivers seem to cause problems with dvd reader so I don't like to use them. The adaptec firewire card uses drivers supplied with Windows Xp. I capture the video with the dv type 2 compressor to the empty slave hard drive with Pinnacle Studio 7. I have also tried Microsoft Movie Maker. Both capture programs yield great captures, but after about 50 min. of capture, the audio and video start to slip out of synch. Pinnacle Studio 7 does not report any dropped frames. I am at a loss as to why I am having this a/v synch problem. The home video tape that I am capturing from is a fairly new recording and plays back pretty well. My video captures get out of synch also when I capture from my vcr's tv tuner. I prefer to capture this way because the video is much better than when I try to capture from my ati aiw.

If anyone can give me some suggestions that might help correct this a/v synch problem, I would appreciate any input.

Thanks for your time.
