    Hi
    Im attempting to convert VHS to MPEG VCD (PAL, not NTSC). The problem is that the sound and video don't sync. After an hour, the sound is about 10 seconds ahead of the video. Im using a Xpert TV-PVR PCI card to capture the VHS recordings. The VCR is connected to the card with a co-ax cable to the arial input of the card. Im using a 32Mb RIVA TNT2 graphics card on a Duron 700 machine with a 40Gb 5400 rpm hard drive and 128 Mb RAM. Could the problem be my sound card? The audio is passed from the tv card to the line-in on my sound card. I have downloaded and installed the lastest drivers for the tv card, but that makes no difference. Could the problem possibly be with playback, and not recording? I've tried different applications for viewing the mpegs, including MS Media Player.

    Actually the video is about 10 seconds ahead of the sound. Maybe its becaus of frames being dropped? Is my PC setup adequate?

    I had a similar problem under XP and found that leaving the Capture work on its own + with High or Realtime priority fixed it.

    To change priority of a process under XP, hit CTRL ALT and DELTE, you should now see the task manager, click processes (if you cant see processes, go to the task manager window and doubleclick the very edge of it and u shud now see processes) right click on the process and change the priority to whatever you want.

    Also just as a side note, if u are using XP, 128mb of ram is not a lot of ram while using XP, you should maybe do some performace tweaking like killing useless processes so that there's more resources for your capture/encode!
