I'm off 0.20-fixes r12172. The hardware is an M2NPV-VM board with NVidia 6150 graphics and an AM2-3600X2 processor. Currently got NVidia driver 9626 and I've also tried enabling UseEvents in my X settings. I didn't enable ""Use Video as the Timebase"" as this appears to speed up the audio slightly changing the pitch. The error output from the frontend is as follows {{{ 2007-02-05 10:09:04.785 Video timing method: USleep with busy wait [mpegts @ 0xb7223db8]Parser not found for Codec Id: 94211 ! 2007-02-05 10:09:06.391 VideoOutputXv: XvMCTex: Init failed 2007-02-05 10:09:06.391 VideoOutputXv: XVideo Adaptor Name: 'NV17 Video Texture' X Error: BadMatch (invalid parameter attributes) 8 Major opcode: 142 Minor opcode: 14 Resource id: 0x190 2007-02-05 10:09:06.804 AFD: Opened codec 0x82fdca0, id(MPEG2VIDEO) type(Video) 2007-02-05 10:09:06.837 AFD: Opened codec 0x9fae370, id(MP3) type(Audio) 2007-02-05 10:09:07.046 Opening OSS audio device '/dev/dsp'. 2007-02-05 10:09:07.051 NVP: Enabling Audio [mpegts @ 0xb7223db8]Parser not found for Codec Id: 94211 !
