OK.. I spoke too soon..
It appears that the drivers ONLY check tables that have the
section_syntax_indicator set.. This is the correct thing to do, but if that 1
bit is screwed up you will be in trouble.. I got a number of tables that were
dropped because of this.. Can you try the attached patch, and let me know if
you get other tables slipping through that are bad? I need to validate the DVB
docs before I use this as a blanket solution hence no commit on this one yet..
