Hi!
Sorry for the delay, I was away for a while.

I downloaded your sample, and my version of dvbcut (r138) *does* detect
the audio track:
PAT: found PMT at pid 49
PMT: found video stream at pid 2048
PMT: found audio stream at pid 2049
And also a lot of weird shit, by the way:
missing frame(s) before B frame 1 (150 != 0)
missing frame(s) before B frame 31 (180 != 0)
missing frame(s) before B frame 61 (210 != 0)
missing frame(s) before B frame 77 (226 != 0)
missing frame(s) before B frame 107 (256 != 0)
missing frame(s) before B frame 137 (286 != 0)
missing frame(s) before B frame 167 (316 != 0)
missing frame(s) before B frame 197 (346 != 0)
missing frame(s) before B frame 211 (360 != 0)
missing frame(s) before B frame 249 (398 != 0)
and so on. Not sure what they're doing there.

Huh? Here's what one of my tools found in the PMT:
# video stream
sv0001.0.stream_type = 02
sv0001.0.stream_type_str = "ISO/IEC 13818 Video"
sv0001.0.elementary_pid = 0800
# audio stream
sv0001.1.stream_type = 81
sv0001.1.stream_type_str = "User Private"
sv0001.1.elementary_pid = 0801
It's all there. No idea why ProjectX doesn't find it. Or your copy of
dvbcut, for that matter.
