Okay, time to play with dvbsnoop to see if you have any
information on your transports.
Make sure your card is tuned to a valid channel and then
shutdown mythbackend.
Run 'dvbsnoop 0x0'
You will get a bunch of lines like...
Program_number: 22080 (0x5640)
reserved: 7 (0x07)
Program_map_PID: 701 (0x02bd)
Pick one of these and then run dvbsnoop on the Program_map_PID
in this case that would be 'dvbsnoop 0x02bd'
Check the output, you will need to see entries underneath
Stream_type loop:
that say
Stream_type: 2 (0x02) [= ITU-T Rec. H.262 | ISO/IEC 13818-2 Video | ISO/IEC 11172-2 constr. parameter video stream]
reserved_1: 7 (0x07)
Elementary_PID: 101 (0x0065)
reserved_2: 15 (0x0f)
ES_info_length: 3 (0x0003)
This is the video stream.
Now you can look to see if there is any data on the stream with
'dvbsnoop -f 0x4d -m 0xff 0x0065'
0x4d is EIT section descriptor
0xff is mask
0x0065 is the PID of the video from above (Elementary_PID: ...)
Try also changing 0x4d to 0x4e
Let me know if you get output from the last commands, either with
0x4d or 0x4e
