What type of audio is being used? In the US the HDTV stations are
using AC3 (either 384Kb/s 5.1 or 192Kb/s 2.0 from what I have seen).

I think there's a slightly later version (0.81.8):
latest version:
Project X 0.81.8.01
I have not researched what the changes were between 0.81.7 and .8

I do the same type of thing. But with SD (Standard Definition
704x480 for NTSC) broadcasts it is not necessary to decode/encode
the video stream - the .m2v and .ac3 files produced by ProjectX are
directly useable for authoring a DVD. For HD (High Definition)
broadcasts a decode/y4mscaler/encode proceedure is needed to convert
from 1920x1080 (1:1 pixels) to widescreen DVD format. The .ac3 audio
file can be used without change.
So far the only problem I have found with ProjectX is that it does
NOT understand 3:2 pulldown so if I try to use ProjectX with a
.mpg file that uses 3:2 pulldown (the original was from film) the
result is junk.
