I'm capturing into full D1 PAL with an ADS DVDExpress, then need to edit.

I have used both TMPEGEnc and Ulead Video 7 and both give the same result.

The audio get's progresively more and more out of sync until it lags the video by a good six seconds at the end, though the original capture is in sync.

The programme is about 2hrs 10mins long.

I think it might be a sample rate inaccuracy in the ADS box, but I don't know how to fix it.

This sorta thing has probably been done to death, but I can't find anything this specific in the search.

TIA.
