Audio async with many apps

[wheeljack12]

I have been recently trying to convert VHS tapes to DVD for life lasting against degradation. Most of it is live sports events. I will post my specs below for more detail. but I have a Visiontek Geforce 4 Ti4600 128 MB vid card and Hauppauge WinTV-PVR-PCI for TV and Capture. FYI, the visontek uses the Vivo tv encoder on the Xtasy everything also. I capture with the WinTV software in MPEG-2 at about 4mbit. When I replay in WinTV or Media Player, all is in Sync. Even when I have created the Project with menus, still in sync. But when the DVD is written, the audio comes 2-3 seconds behind the video. This happens when using a DVD-ROM on pc or home player. Also, I have tried making the DVD after capture from Ulead's DVD Movie Factory and Sonic's DVDit PE with the same result. My question is the Vivo on the Geforce and the Wintv Capture hardware and drivers somehow conflicting with each other possibly slowing capture causing a async MPEG. Although the hard drive can play back properly in sync since it has the speed to compensate can this be? I mean where the final product is async because of two capture chips are active and maybe possibly causing it? If this not the case, what other possible explanations are there? I am curious since I have killed 4 DVD-R ($40 US) and it is becoming a expensive effort. Just to add, if there is hardware change needed, how would a ATI ALL-IN-WONDER 8500DV be useful in the Sync problem? See, I watch TV alot on the PC and I play a fair amount of games to boot.

In the same boat as I am trying to back up VHS stuff onto DVD. Capturing 2/4/6 MBps using Hauppage Wintv PVR USB with no problems. Prior to authoring, playback on Ulead video and audio appear to be in sync from beginning to end.

Once the file has been authored using ULead (have also tried DVDit without success), audio gradually falls out of sync with video. One theory I have is that sample frequency on original raw mpeg2 file may be being captured as 44.1KHz (for VCD and SVCD), however for DVD I think 48KHz is required (although I could be talking bollocks here) but I don't know how to fix it . I am incidentally using a DVD-RW on a Firewire LAcie/Pioneer DVD-103 writer.

To back the gradual audio sync degradation up I captured 30 seconds of mpeg2 at 6 MBps and burnt this to DVD using ULead and was ok on PC and stand alone player ie all in sync. It may be worth you trying this and seeing if you get similar results with a DVD-RW.

Sorry I can't be more help as I need a result on this DVD recording caper also!
