[mythtv-users] Trouble with DVB-C

[Oyvind Eriksen]

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.
