AC3 or MP2 audio i got from BeSweet doesn't play in my DVD Player or WinDVD 5+??

Some DVD Players dont support audio from BeSweet and the reason for that I don't know. However, You can use AC3Enc (it comes with Sonic Scenarist) to encode an ac3 file from a wav source that will be more supported in DVD Players. Pioneer DVD Players are known to have this problem!
