Audio Out of Sync after 40 mins of capturing

[Dolleck]

Anyone else have this problem?
I have an ATI TV Wonder.

Using MMC7.1
I was capturing MPEG 1 6m/s 352x240 and after about 40 mins the audio goes out of sync with the video.
When the file starts off everything is fine. But after 40 mins or so you hear the audio first then about half a second later you see the lips move. Then at about an hour its a whole second off.

I have a PIII 700, 384 megs of ram, Ata 100, but have to use it at udma 33, 7200 30 gig hard drive.
My mother board is rather old, Abit Bx6.

Thanks.

most of the time it's because of your harddisk,try defrag it

Thanks for the defrag thought unfortunately it didnt help.
I reformatted my drive. Reinstalled Win98 and everthing else.
Although I've managed to keep audio in sync while capturing by keeping the VCD standard correct, It still gets out of sync when I use Virtual dub to edit out commercials and reencode with mpeg encoder.
Oh well.. the life of a newbie.
