[mythtv] Experimental HDTV Recording patch updated

Does your recorded stream contain PMT and PAT tables? Myth needs those,
but I'm not sure if mplayer does. If you could send me the output of
"mythbackend -v record" on one of those non-working recordings might
help.

The only thing I can think of is that the new PAT/PMT code isn't
finding the stream. Make sure that you have the channel in the format
"12-2" where the second number is the program id. The PAT parser is
different and will deal with program lookup failures differently. But it
should report a failure in the log.

The new code tries to parse the tables completely and then use that
information to build new tables, instead of just rewriting the old
tables.
