Could you please attach a copy of the logfile generated from

mythtv-setup --verbose siparser,record,channel

to http://svn.mythtv.org/trac/ticket/1485

and also the output of

dvbsnoop -n 1 -nph 0x10

to the ticket. You will need to use tzap to tune to a channel before
using dvbsnoop.

I'm actively looking at this area at the moment, so the info you
provide will help.
