PowerDirector 2.0 PRO is nice program (scene autodetection for menu and chapters) except it encodes audio in PCM uncompressed format even if you feed in mpegs with mp2, 48kHz, 224kbps audio.

1.)How to swap the audio stream in the finished VOBs with mp2 or ac3 version without having to re-author again with different authoring tool and making chapters again and menus again?

2.)To formally have a legal DVD - mp2 audio track is OK but only if there is also one track ac3 or/and PCM. How to 'multiplex in' short PCM fragment to fulfill the demand and not waste the space with a track of a full lenght?(~1.5G!)

3.)Would the standalone DVD players accept DVD with only one audio stream - mp2 type and question 2.) is irrelevant?
