Description
I have a mythbackend version 0.20.20070821-1 installed on a Debian Etch (stable) system. Sometimes I have to restart the backend because I see a very very scrambled image in live TV (you can see a photo here http://img112.imageshack.us/img112/8436/image00163av1.jpg).
If I stop and restart the mythbackend all return to works good.
When I see the scrambled images I have these logs on the backend:

"Nick F" answered me this in the MythTV mailing list:
Are you using a CAM by any chance? I was finding a similar problem. I adjusted the usleep value in the dvbcam module and it helped. I still need to reset my backend every two weeks or so when I get a similar scrambled picture problem. In my case it's a DVB problem, not a myth problem.
I haven't solved this problem yet and I am available for testing.

The CAM code has changed a lot as part of the multirec project + we're no longer fixing 0.20 specific problems.
Hi,
Are you using EIT? I had this problem for a while but it went away when I disabled EIT. When I get home I can add the actual error message that was appearing during the EIT scan (something about the CAM being locked).
