    Hello, I am first time user and DVD author at least for education support at school and home use, limited business use for now. I recently took a mpg file created from ATI AIW 9600 Radeon card capture. It was 1.25 hour long. I trimmed okay to match capacity of DVD disk, played bac kokay to make sure video and audio stayed in sync, it did. and played back to match capacity of DVD. Once it played back both in PC and Cyberhome DVD PLayer, tested 2 of them, audio became out of sync about 10 minutes in to playing, then I would pause, then restart, audio would be in sync, then 10 min later noticeably audio would be slighly off again. No frames were dropped that I am aware of within body of 1 hour of video. I would like to know if creating chapters as opposssed to leaving one large IFO file on DVD creation would resolve audio from getting out of sync. It was captured in 44,100 hz 640x480 resolution. Played back on PC prior to authoring project, no sync problems all the way through. Any ideas would be apprecaited. I used Roxio's DVD BUilder to master the first attempt. Thank you for your assistance. Topic was Regan Sunset Funeral Service.

    Well, for starters, the file isn't DVD-compliant. Audio needs to be sampled at 48 KHz and the resolution isn't a standard DVD resolution.

    Read this first:

    On the sync issue, if you're pausing and getting apparent good sync after restarting, the problem lies with the player and not the video. It's never a good idea to judge sync using the MPEG with a software player.

    You really need to author the DVD (generate .VOB, etc. files) and open those with a DVD player such as PowerDVD or WinDVD, to evaluate sync.

    Adding chapter points won't do anything for sync problems.

    Try recapturing at a DVD resolution, following the guidelines for settings for res. and audio. Then author and play back the files. You may not even have a sync problem

  3. Yea, you want to render that file with something like TMPGENC. If you are already rendering it that could be your problem, because poor encoders will desync your audio/video. I have had bad experience with WinDVD Creator doing that, so you may want to steer clear of it.

    Thank you for the gracious feedback. I will certainly get busy on educating myself on how to capture and in what resolution and bit rate for audio. The thing that bothered me though is why there was no options to change on capture software within ATI application suite. I willcheck out the On DEmand Producer for windows, the the other apps mentioned. Without seeing any notable option changesI fgured defaults were fine as given. I willlet you know of my next steps taken on a test. Thanks again
