Next message: [mythtv-users] Scheduled recording & playback OK, but no LiveTV (0.20-fixes fresh install?) Hi folks I'm puzzled. After a clean install (following Jarod's doc), I'm running 0.20-fixes (protocol 31) from ATRPMS and mostly all is well. The puzzle is that while I can schedule recordings and play them back flawlessly, including playing the in-progressrecording, I'm unable to enter LiveTV. The screen goes dark, I can see the external channel change script run in the logs, and visually on my cable box, but then I get unceremoniously dumped back to the menu. I don't believe I'm in the 'missing startchan; delete cards, sources & channels; reconfigure' bucket. (As a precaution I tried that fix, no joy). I've run the backend and frontend with "-v all" but I don't see anything that looks conclusive - I'm curious about the socket connection closing? Full log attached. (N.B. this session was initiated from my Mac frontend, but I get the same problem when the frontend is local to the backend.) 2006-10-03 23:48:06.838 TVRec(1): SetFlags(RunMainLoop,) -> RunMainLoop, 2006-10-03 23:48:06.838 TVRec(1): ClearFlags(ExitPlayer,FinishRecording,) -> RunMainLoop, 2006-10-03 23:48:31.931 TVRec(1): Changing from None to WatchingLiveTV 2006-10-03 23:48:31.932 TVRec(1): ClearFlags(FrontendReady,CancelNextRecording,) -> RunMainLoop, 2006-10-03 23:48:31.932 TVRec(1): SetFlags(AskAllowRecording,) -> RunMainLoop,AskAllowRecording, 2006-10-03 23:48:31.932 TVRec(1): Request: Program(no) channel() input() flags(LiveTV,) 2006-10-03 23:48:31.933 TVRec(1): HW Tuner: 1->1 2006-10-03 23:48:31.933 TVRec(1): ClearFlags(PENDINGACTIONS,) -> RunMainLoop,AskAllowRecording, 2006-10-03 23:48:38.981 TVRec(1): ClearFlags(NeedToStartRecorder,) -> RunMainLoop,AskAllowRecording, 2006-10-03 23:48:38.981 TVRec(1): SetFlags(NeedToStartRecorder,) -> RunMainLoop,AskAllowRecording,NeedToStartRecorder, 2006-10-03 23:48:38.981 TVRec(1): Starting Recorder 2006-10-03 23:48:39.001 TVRec(1): CreateLiveTVRingBuffer() 2006-10-03 23:48:39.001 TVRec(1): GetProgramRingBufferForLiveTV() 2006-10-03 23:48:39.112 TVRec(1): StartedRecording(0x8767700) fn(/mnt/media/video/1005_20061003234839.mpg) 2006-10-03 23:48:39.227 TVRec(1): SetFlags(RingBufferReady,) -> RunMainLoop,AskAllowRecording,NeedToStartRecorder,RingBufferReady, 2006-10-03 23:48:39.267 TVRec(1): SetFlags(CancelNextRecording,) -> RunMainLoop,CancelNextRecording,AskAllowRecording,NeedToStartRecorder,RingBufferReady, *** Below be dragons? *** 2006-10-03 23:48:39.267 write -> 16 2 ok 2006-10-03 23:48:39.267 MythSocket(8767090:16): state change Connected -> Idle 2006-10-03 23:48:39.267 MythSocket(8767090:-1): cb->connectionClosed() 2006-10-03 23:48:39.267 StopLiveTV(void) curRec: 0x8767700 pseudoRec: 0 2006-10-03 23:48:39.268 MSqlQuery: SELECT recorded.chanid,starttime,endtime,title, subtitle,description,channel.channum, channel.callsign,channel.name,channel.commfree, channel.outputfilters,seriesid,programid,filesize, lastmodified,stars,previouslyshown,originalairdate, hostname,recordid,transcoder,playgroup, recorded.recpriority,progstart,progend,basename,recgroup FROM recorded LEFT JOIN channel ON recorded.chanid = channel.chanid WHERE recorded.chanid = '1005' AND starttime = '2006-10-03T23:48:39' ; 2006-10-03 23:48:39.268 MSqlQuery: SELECT commflagged, cutlist, autoexpire, editing, bookmark, stereo, closecaptioned, hdtv FROM recorded LEFT JOIN recordedprogram ON (recorded.chanid = recordedprogram.chanid AND recorded.starttime = recordedprogram.starttime) WHERE recorded.chanid = '1005' AND recorded.starttime = '2006-10-03T23:48:39' ; 2006-10-03 23:48:39.316 MPEGRec(/dev/video0): VBI service:1, packet size:0, io size:0 *** Above be dragons? *** 2006-10-03 23:48:39.317 TVRec(1): SetFlags(RecorderRunning,RingBufferReady,) -> RunMainLoop,CancelNextRecording,AskAllowRecording,NeedToStartRecorder,RecorderRunning,RingBufferReady, 2006-10-03 23:48:39.317 TVRec(1): ClearFlags(NeedToStartRecorder,) -> RunMainLoop,CancelNextRecording,AskAllowRecording,RecorderRunning,RingBufferReady, 2006-10-03 23:48:39.318 TVRec(1): Changing from WatchingLiveTV to None 2006-10-03 23:48:39.318 TVRec(1): ClearFlags(FrontendReady,CancelNextRecording,) -> RunMainLoop,AskAllowRecording,RecorderRunning,RingBufferReady, 2006-10-03 23:48:39.319 TVRec(1): SetFlags(AskAllowRecording,) -> RunMainLoop,AskAllowRecording,RecorderRunning,RingBufferReady, 2006-10-03 23:48:39.319 TVRec(1): Request: Program(no) channel() input() flags(KillRec,KillRingBuffer,) 2006-10-03 23:48:39.963 TVRec(1): ClearFlags(RecorderRunning,) -> RunMainLoop,AskAllowRecording,RingBufferReady, 2006-10-03 23:48:40.003 TVRec(1): FinishedRecording(Ideal) in recgroup: LiveTV 2006-10-03 23:48:40.008 TVRec(1): ClearFlags(RecorderRunning,) -> RunMainLoop,AskAllowRecording,RingBufferReady, 2006-10-03 23:48:40.008 TVRec(1): Tearing down RingBuffer 2006-10-03 23:48:40.010 TVRec(1): ClearFlags(PENDINGACTIONS,) -> RunMainLoop,AskAllowRecording,RingBufferReady, (Full log is available but was too big - my post was rejected.)

A couple of months ago, I finally broke down and bought an nVidia 
card to replace the ATI graphics on my motherboard.

I've got to say that the quality of the Linux driver support is night 
and day. Whereas ATI's driver has known bugs that go for years 
without being fixed, nVidia's is rock-solid, easy to install, and 
extremely well documented.

As far as your fan quandary goes, you should know that in some cases, 
it is possible to run a graphics card without the fan. If you are 
only ever doing 2D graphics and not doing intensive things like XvMC, 
then you may be able to unplug the fan without doing any harm to the 
GPU. That said, don't blame me if your card fries when you try it :-).
