Well after much finagling I was able to get a fresh Gentoo 2008.0 install onto my disk alongside Ubuntu. Using the nVidia driver supplied by the repository (same version as in Ubuntu), along with my custom kernel and the v4l-dvb repository.
I was able to get around the audio write errors above by explicitly setting my audio device in Mythtv to /dev/dsp and making sure KDE/aRTS was set to release the sound card after a few seconds. Same setting on both distros. However, the stream of "prebuffering pause" messages still persists only under Ubuntu - the Gentoo side seemed more or less devoid of these messages and the video was as smooth as I normally expected it to be. Any amount of activity (such as a window gaining or losing focus) here on the Ubuntu side will set off a stream of those messages, the video and audio still get a little choppy, and if it gets too severe, mythfrontend segfaults. I might be able to avoid this by enabling realtime priority, but the last time I did that, it caused a hard lock. It seems that the XvMC multi-core crash exists on Gentoo as well (odd, I could have sworn I used it before). I guess that technically makes this bug report invalid. -- Segfault on XvMC + SMP (if two or more cores are enabled) https://bugs.launchpad.net/bugs/249203 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
