I have some AVIs which i converted to MPEGs with Winavi. Then I demultiplexed them with TMPGEnc. When I imported them into DVD Lab Pro, for authoring onto dvds, I got the message that the audio tracks were 44.1Khz and that I needed to convert them to 48. So I used the audio transcode tool that comes bundled with DVD Lab. It worked for the first 3 avis, but for the last one, when it transcodes it results in an mpa file that is 0 seconds long (it should be an hour and 3 minutes). Anybody have any ideas?
I'd recommend trying BeSweet to resample. If it still doesn't work there's probably something wrong with the audio stream. You could also try importing the muxed MPEG as an asset in DVD-Lab and letting it demux and resample.
