If you try to play the file in mplayer it detects the audio stream as DD 5.1,
but never gives any audio.. Xine attempst to play it but its very choppy.. This
LOOKS like it was created using the transform.c code in the 3.3 or 3.4 patch..
Marcus Metzler sent me a patch to hopefully fix this properly.. He can
elaborate more, but said he found a bug that corrupted AC3 in some way..

Also we are almost done with saving a stripped ts which should create the same
files as the PCHDTV creates..

Hopefully this will fix your problem.  In a day or two the inital patch will go
on here to see if it can get put into myth-cvs..
