| Post subject: | Problem with one channel |
Has anyone seen this? On my system: recording, live tv, etc. all work fine, except for one channel, PBS-HD (of course the most important one). If I go to live TV, and switch to this channel, the screen goes black, the OSD shows up , but no video or audio. It never times out. I have to ssh in, and reboot. When I record, this is what shows up in the logs: 2005-11-02 10:59:31.060 Started recording "Nova" on channel: 1021 on cardid: 1, sourceid 1 2005-11-02 10:59:31.067 DVB#0 Using DVB card 0, with frontend LG Electronics LGDT3303 VSB/QAM Frontend. 2005-11-02 10:59:31.073 DVB#0 WARNING - Symbol Rate setting (0) is out of range (min/max:5056941/10762000) 2005-11-02 10:59:31.121 Changing from None to RecordingOnly 2005-11-02 10:59:31.148 Prog title: Nova 2005-11-02 10:59:31.152 DVB#0 Using DVB card 0, with frontend LG Electronics LGDT3303 VSB/QAM Frontend. 2005-11-02 10:59:32.169 DTVsm: Ignoring encrypted program 2005-11-02 10:59:34.183 TVRec: Timed out waiting for lock -- aborting recording 2005-11-02 10:59:34.211 TVRec: StartRecorderPost(): aborting recording For a channel that works, here's the log: 2005-11-01 19:59:31.025 Started recording "My Name Is Earl" on channel: 1111 on cardid: 1, sourceid 1 2005-11-01 19:59:31.036 DVB#0 Using DVB card 0, with frontend LG Electronics LGD T3303 VSB/QAM Frontend. 2005-11-01 19:59:31.049 DVB#0 WARNING - Symbol Rate setting (0) is out of range (min/max:5056941/10762000) 2005-11-01 19:59:31.131 Changing from None to RecordingOnly 2005-11-01 19:59:31.158 Prog title: My Name Is Earl 2005-11-01 19:59:31.166 DVB#0 Using DVB card 0, with frontend LG Electronics LGD T3303 VSB/QAM Frontend. 2005-11-01 19:59:31.773 DVB#0 DVB SI Table Parser Started 2005-11-01 19:59:31.921 Waiting for recorder to start 2005-11-01 19:59:31.923 DVB#0 Data read from DMX - This is for debugging with tr ansform.c 2005-11-01 19:59:31.926 Recorder started 2005-11-01 19:59:32.956 MainServer::HandleAnnounce Playback 2005-11-01 19:59:32.963 adding: mythtv as a client (events: 0) 2005-11-01 20:05:04.867 MainServer::HandleAnnounce Playback 2005-11-01 20:05:04.873 adding: mythtv as a client (events: 0) 0: start_time: 2534.724 duration: 29.937 1: start_time: 2534.680 duration: 29.935 stream: start_time: 28163.113 duration: 333.120 bitrate=13689 kb/s 2005-11-01 20:05:05.927 AVFD: Opened codec 0xb2205eb0, id(MPEG2VIDEO) type(Video ) 2005-11-01 20:05:05.937 AVFD: Opened codec 0xb2222e60, id(AC3) type(Audio) 2005-11-01 20:05:06.506 MainServer::HandleAnnounce FileTransfer 2005-11-01 20:05:06.516 adding: mythtv as a remote file transfer 0: start_time: 2845.807 duration: 167.039 1: start_time: 2845.763 duration: 167.046 stream: start_time: 31619.585 duration: 1856.478 bitrate=14573 kb/s 2005-11-01 20:05:06.983 AVFD: Opened codec 0xb220e530, id(MPEG2VIDEO) type(Video ) 2005-11-01 20:05:07.000 AVFD: Opened codec 0xb2205eb0, id(AC3) type(Audio) 2005-11-01 20:05:07.319 MainServer::HandleAnnounce FileTransfer 2005-11-01 20:05:07.328 adding: mythtv as a remote file transfer 2005-11-01 20:18:22.783 MainServer::HandleAnnounce Playback 2005-11-01 20:18:22.802 adding: mythtv as a client (events: 0) 2005-11-01 20:18:43.257 MainServer::HandleAnnounce Playback 2005-11-01 20:18:43.264 adding: mythtv as a client (events: 0) 2005-11-01 20:30:30.005 Finished recording My Name Is Earl on channel: 1111 2005-11-01 20:30:30.015 Changing from RecordingOnly to None 2005-11-01 20:30:30.015 Received U_R_S: 1 1111 2005-11-01T20:00:00 -3 2005-11-01 20:30:30.044 Reschedule requested for id 0. 2005-11-01 20:30:30.391 Scheduled 98 items in 0.3 = 0.02 match + 0.33 place Here's my questions: It looks like it's not locking on to PBS. Looking at signal strength on my sony tv, it's at 90 something % for all channels, PBS not more or less. 1. What is the "symbol rate setting" and why is it out of range. Where is that set up? 2. I'm guessing that the line "Ignoring encrypted program" is because it's not locking on, as this is all OTA. I don't have cable. Is that likely? I'm running: R5A22 MSI NEO-3 motherboard P4 3GHz Geforce MX4000 video DVI out DViCO Fusion 5 Lite tuner HD3000 tuner (alternately) Any ideas? |

It looks like I may have found the source to this problem. At least the encrypted part: From the svn tracker for mythtv: "It appears some ATSC channels are adding an MPEG CA encryption descriptor with a System ID of 0x0 to indicate no-encryption. We need to handle this as a non-encrypted stream." http://svn.mythtv.org/trac/ticket/336 This links to some code replacement for the source file mpegtables.cpp. Yet another area I'm completely unaware of. How do I go about updating this? It seems this would be something that is affecting more than just me? Anybody else in the Minneapolis area seeing this? |

I don't think you want to update to svn right now, as livetv is currently disabled. |
