In the afore mentioned program I am trying to put together an hour's worth of my short films, but after the DVD has burned the sound starts out in the proper place but slowly starts lagging behind. By the end it is about 5 seconds off its actual spot. Even if I export the whole thing as one file, it does the absolute same thing. What could I possibly be doing wrong?
Check your source video using GSpot or MediaInfo - you will probably find it is NTSC at 29.97 fps Make sure you have the latest patch installed - the problem was fixed in a previous patch.
If the source is PAL then try recreating the frametables by right clicking video clip(s)
