[mythtv-users] Trouble with DVB-C

I've done some more research and started the backend with the "most"
debug level.
The log file was too large to attach but is available at
http://www.eriksen.cn/backend-verbose-most.txt
What I noticed from the log are the messages "PESPacket: Failed CRC
check" and "AddTSPacket: Out of sync!!! Need to wait for next
payloadStart" which is repeating countless times until, I assume, it
gives up.
Somebody which is used to read mythbackend logs may see something else
I've missed.
