In case of multi-program TS, there are not conflicting, but complementary PMTs.
I think it would be correct if you change flags when you have found
PMT for every program mentioned in PAT, not just after finding one
PMT.

Otherwise, i admire the intention of patch to shorten the time for
MPEG TS structure recognition.
