Ok, I've been watching verbose output till my eyes are bleeding, and I have a couple things to add / clarifiy:
1. With XvMC the lockups ONLY occur on my frontend when the OSD is fading out after a FFW / RW / etc. 2. Without XvMC the lockups occur when FFW/RW. I have a pile of -v debug, but here's the one thing that jumped out: 2005-02-14 20:45:26.498 Timed out waiting for free video buffers. Because the audio is showing "Paused" at this point, it doesn't appear to be an audio problem. I did try the patch suggested in another thread with no help. I'm not able to get the data I wanted from GDB, call it inexperience, so unfortunately, the best I have is from -v playback from mythfrontend. It doesn't appear to be a network or backend problem, that I can tell. I had mythbackend -v all and the logging simply stops. Once the frontend is killed, it shows the frontend disconnecting, so it doesn't appear the backend locked. Anyway, here's the logs: [EMAIL PROTECTED] ~]$ mythfrontend -v playback,osd,file,network 2005-02-14 21:25:20.849 mythfrontend version: 0.17.20050130-1 www.mythtv.org 2005-02-14 21:25:20.849 Enabled verbose msgs : important general playback osd file network 2005-02-14 21:25:21.092 Switching to square mode (Iulius) 2005-02-14 21:25:21.379 Registering Internal as a media playback plugin. 2005-02-14 21:25:21.415 Registering MythDVD DVD Media Handler as a media handler 2005-02-14 21:25:21.524 generating cache image for: /usr/local/share/mythtv/themes/default/blank.png 2005-02-14 21:25:26.545 All Programs 2005-02-14 21:25:27.118 Connecting to backend server: 192.168.2.222:6543 (try 1 of 50) 2005-02-14 21:25:27.119 write->10 21 MYTH_PROTO_VERSION 14: 2005-02-14 21:25:27.126 Using protocol version 14 2005-02-14 21:25:27.126 write->10 24 ANN Playback frontend1 0: 2005-02-14 21:25:27.178 write->10 21 QUERY_RECORDINGS Play: 2005-02-14 21:25:27.468 write->13 24 ANN Playback frontend1 0: 2005-02-14 21:25:27.481 write->14 74 ANN FileTransfer frontend1[]:[]/2081_... 2005-02-14 21:25:28.069 write->13 45 QUERY_FILETRANSFER 47[]:[]REQUEST_BLO... 2005-02-14 21:25:28.076 Read(): reqd=0, rcvd=0, rept=0, error=0 2005-02-14 21:25:28.076 write->13 30 QUERY_FILETRANSFER 47[]:[]DONE: 2005-02-14 21:25:28.083 write->10 632 QUERY_GENPIXMAP[]:[]CSI: Miami[]:[]Id... 2005-02-14 21:25:30.945 write->13 24 ANN Playback frontend1 0: 2005-02-14 21:25:31.379 write->14 74 ANN FileTransfer frontend1[]:[]/2081_... 2005-02-14 21:25:31.388 write->13 49 QUERY_FILETRANSFER 47[]:[]REQUEST_BLO... 2005-02-14 21:25:31.413 Read(): reqd=28257, rcvd=28257, rept=28257, error=0 2005-02-14 21:25:31.413 write->13 30 QUERY_FILETRANSFER 47[]:[]DONE: 2005-02-14 21:25:31.843 write->13 24 ANN Playback frontend1 0: 2005-02-14 21:25:31.907 write->14 74 ANN FileTransfer frontend1[]:[]/1015_... 2005-02-14 21:25:31.942 write->13 49 QUERY_FILETRANSFER 47[]:[]REQUEST_BLO... 2005-02-14 21:25:31.960 Read(): reqd=32601, rcvd=32601, rept=32601, error=0 2005-02-14 21:25:31.960 write->13 30 QUERY_FILETRANSFER 47[]:[]DONE: 2005-02-14 21:25:31.977 24 ANN Playback frontend1 1 2005-02-14 21:25:33.110 write->13 24 ANN Playback frontend1 0: 2005-02-14 21:25:33.128 write->14 74 ANN FileTransfer frontend1[]:[]/2094_... 2005-02-14 21:25:33.137 write->13 49 QUERY_FILETRANSFER 47[]:[]REQUEST_BLO... 2005-02-14 21:25:33.145 Read(): reqd=25410, rcvd=25410, rept=25410, error=0 2005-02-14 21:25:33.145 write->13 30 QUERY_FILETRANSFER 47[]:[]DONE: 2005-02-14 21:25:34.174 write->13 24 ANN Playback frontend1 0: 2005-02-14 21:25:34.206 write->14 74 ANN FileTransfer frontend1[]:[]/2081_... 2005-02-14 21:25:34.235 write->13 49 QUERY_FILETRANSFER 47[]:[]REQUEST_BLO... 2005-02-14 21:25:34.243 Read(): reqd=18855, rcvd=18855, rept=18855, error=0 2005-02-14 21:25:34.243 write->13 30 QUERY_FILETRANSFER 47[]:[]DONE: 2005-02-14 21:25:36.171 write->13 24 ANN Playback frontend1 0: 2005-02-14 21:25:36.470 write->14 74 ANN FileTransfer frontend1[]:[]/1005_... 2005-02-14 21:25:36.577 write->13 49 QUERY_FILETRANSFER 47[]:[]REQUEST_BLO... 2005-02-14 21:25:36.585 Read(): reqd=25498, rcvd=25498, rept=25498, error=0 2005-02-14 21:25:36.585 write->13 30 QUERY_FILETRANSFER 47[]:[]DONE: 2005-02-14 21:25:36.801 write->10 598 QUERY_CHECKFILE[]:[]CSI: Crime Scene ... 2005-02-14 21:25:36.942 AVFD 2005-02-14 21:25:36.942 AVFD: Opening Stream #0: codec id 2 2005-02-14 21:25:36.944 Using libmpeg2 for video decoding 2005-02-14 21:25:36.945 detectInterlace(Detect Scan, Detect Scan, 29.97, 480) ->Interlaced Scan 2005-02-14 21:25:36.945 Interlaced: Interlaced Scan video_height: 480 fps: 29.97 2005-02-14 21:25:36.945 AVFD: Looking for decoder for 2 2005-02-14 21:25:36.945 AVFD 2005-02-14 21:25:36.945 AVFD: Opening Stream #1: codec id 86016 2005-02-14 21:25:36.945 AVFD: Looking for decoder for 86016 2005-02-14 21:25:36.947 Estimated bitrate = 16384 2005-02-14 21:25:37.218 Position map filled from DB to: 7184 2005-02-14 21:25:37.218 SyncPositionMap prerecorded, from DB: 7185 entries 2005-02-14 21:25:37.219 Position map found 2005-02-14 21:25:37.224 Opening audio device '/dev/adsp'. 2005-02-14 21:25:37.225 Opening OSS audio device '/dev/adsp'. 2005-02-14 21:25:37.236 Over/underscan.
