^^^^ this type is certainly not in any official tables

The problem is that the PMT is valid, but the stream type
of 0x80 isn't mapped to MPEG2 video (should it? I can't
find any indication but haven't looked hard). So dvbcut
drops the entire PMT information, and later fails
to auto-detect the audio because of unaligned syncwords.
I think some information is better than nothing: check_si_tables()
could process the audio streams and still return false, so that the
auto-detection finds the rest. Patch appended (with the 0x80 type
commented, this could be an alternative)-- maybe I overlooked
something this could break..
Regards,
Wolfram
