I suspect this table 0xF0 might have something to do with it.. I don't know what
this table is, and it should have never been loaded.. Could be a crc error that
snuck in, or crc checking may be turned off (I turned it off for some ATSC
testing and its possible that it remains in the code even though it shouldn't).

Can you dump your dvb_transport table from the database and see if anything is
clearly wrong?  All of the tables are human readable and im curious what
happened here..  Maybe looking at the dump will give some insight..

Can you send me a dump of this SDT table from dvbsnoop?  Ive never seen SDT
channel names like this with extra characters.. Is there some other know reason
for these to be in there?

Looks like something happened with DVB Cam.. I haevn't touched this code.. You
could try commenting out the DVBCam references in dvbchannel and see if this
takes away your error.. I can't tell anything from your backtrace..
