upon an update to 0.19 mythtv failed utterly. I dropped the mythconverg database, unmerged mythtv emerged mythtv 0.19 and followed the setup directions. the result was no sound and no ability to change channel in Livetv, an attempt to change channel resulted in picture freeze followed by spontaneous shutdown. cleanup and retry using 0.19-r1 gave same result. during reboots mythbackend start reported unable to chdir. backend would require manual start. running mythtv would cause backend to report: " amd64 ~ # mythbackend 2006-02-23 11:06:18.850 Using runtime prefix = /usr 2006-02-23 11:06:18.862 New DB connection, total: 1 2006-02-23 11:06:18.869 Connected to database 'mythconverg' at host: localhost 2006-02-23 11:06:18.873 Current Schema Version: 1123 Starting up as the master server. 2006-02-23 11:06:18.880 New DB connection, total: 2 2006-02-23 11:06:18.880 Connected to database 'mythconverg' at host: localhost 2006-02-23 11:06:18.901 New DB connection, total: 3 2006-02-23 11:06:18.902 Connected to database 'mythconverg' at host: localhost 2006-02-23 11:06:18.915 New DB scheduler connection 2006-02-23 11:06:18.916 Connected to database 'mythconverg' at host: localhost 2006-02-23 11:06:18.922 mythbackend version: 0.19.20060121-2 www.mythtv.org 2006-02-23 11:06:18.922 Enabled verbose msgs: important general 2006-02-23 11:06:18.922 AutoExpire: Found 1 recorders w/max rate of 72 MiB/min 2006-02-23 11:06:18.923 AutoExpire: Required Free Space: 2.1 GB w/freq: 10 min 2006-02-23 11:06:20.924 Reschedule requested for id -1. 2006-02-23 11:06:21.009 Scheduled 12 items in 0.1 = 0.07 match + 0.02 place 2006-02-23 11:06:21.011 Seem to be woken up by USER 2006-02-23 11:06:28.881 Running HouseKeeping 2006-02-23 11:06:47.469 MainServer::HandleAnnounce Monitor 2006-02-23 11:06:47.469 adding: amd64 as a client (events: 0) 2006-02-23 11:06:47.490 MainServer::HandleAnnounce Monitor 2006-02-23 11:06:47.490 adding: amd64 as a client (events: 1) 2006-02-23 11:06:47.495 MainServer::HandleAnnounce Playback 2006-02-23 11:06:47.495 adding: amd64 as a client (events: 0) 2006-02-23 11:06:47.501 TVRec(1): Changing from None to WatchingLiveTV 2006-02-23 11:06:47.575 Unknown video codec 2006-02-23 11:06:47.575 Please go into the TV Settings, Recording Profiles and 2006-02-23 11:06:47.575 setup the four 'Software Encoders' profiles. 2006-02-23 11:06:47.575 Assuming RTjpeg for now. 2006-02-23 11:06:47.575 NVR: Error, unknown audio codec 2006-02-23 11:06:47.575 NVR::AudioInit() This Unix doesn't support device files for audio access.

Your database is not setup correctly and your mythtv install is not configured at all. Your capture card is not configured properly. YOu'll probably need to delete the database entirely and start all over. Fix all of the above first and try again. Unix not supporting the device is a result of not including the OSS compat layer on top of ALSA in either the kernel or the ALSA driver ebuild. A config that is not really recommended since some apps still want OSS. However I have fixed that with an experimental patch in mythtv-0.19_p9163. However, just switching to that version won't fix any of the issues for you. Do the above 3 steps first.
