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: 2007-08-07 20:53:54.510 MainServer::HandleAnnounce Playback 2007-08-07 20:53:54.511 adding: camera as a client (events: 0) 2007-08-07 20:53:54.514 TVRec(1): Changing from None to WatchingLiveTV 2007-08-07 20:53:54.515 TVRec(1): HW Tuner: 1->1 2007-08-07 20:53:57.057 Finished recording Soliti ignoti Identità nascoste: channel 4401 2007-08-07 20:53:57.127 Finished recording Soliti ignoti Identità nascoste: channel 4401 2007-08-07 20:53:57.143 Preview Error: Previewer file '/video/record/4401_20070807205354.mpg' is not valid. 2007-08-07 20:53:57.165 MainServer::HandleAnnounce Playback 2007-08-07 20:53:57.166 adding: camera as a client (events: 0) 2007-08-07 20:53:57.168 MainServer::HandleAnnounce FileTransfer 2007-08-07 20:53:57.169 adding: camera as a remote file transfer 2007-08-07 20:54:00.410 Expiring Soliti ignoti Identità nascoste from mar ago 7 20:30:00 2007, 6 MBytes, forced expire (LiveTV recording) 2007-08-07 20:54:29.297 TVRec(1): Changing from WatchingLiveTV to None 2007-08-07 20:54:29.368 Finished recording Soliti ignoti Identità nascoste: channel 4401 ""Nick F"" answered me this in the MythTV mailing list: > Are you using a CAM by any chance?
