    Hi
    I have recently purchased the Dazzle Hollywood DV-Bridge hardware so that i can convert all my old home VHS videos to DVD.

    I am now familiar (i think) with the methods of converting using the following software:

    Capturing using Dazzle Main Actor
    Convert to MPEG II using TMPeg Plus @ CBR 8000 Kbps
    finally setting up menus and burning to disk using Ulead DVD MovieFactory.

    All appears successful... but... When i play back on any Standard DVD Player, i notice the sound quality on many sections of the playback sound like its playing under water.

    I play back the original VHS Tape on my VCR, and the sound is fine.

    Anyone advise me on this?

    Thanks alot

    What format are you using for the audio?? With tmpgenc try something like stereo mpeg-1 L2, at least 192 kbit/sec and 48 000 HZ format. If you used 44.1 or a lower rate that could affect the sound.

    If the source is more audio based (e.g. concerts) up the audio bitrate and lower the video rate, there are bitrate calculator around to help you get the optimum rates.

    Ideally, capture at 48KHz. The integral sample conversion from 44.1KHz within TMPGenc was sup-par when I last used it.

    There was a nice external plug-in to use but I don't recall the name. I think apparently the sample rate conversion may have been improved in the last few releases though.

    Alternatively, use VirtualDub to open the captured .AVI, set audio processing to do a high-quality 48KHz resample and use File, Save WAV file. Then select the WAV file after selecting the original .AVI in TMPGenc.

    regards,
    Rob.

    Thanx for your replies.

    I now know what the problem was.... I recaptured the VHS Video onto a freshly defragmented Hard drive and set the System Priority (for the capture software) to realtime.

    I Before doing this i discovered i was getting too many dropped frames - this is what caused the sound problems.

    thanks again
