Generally people try swapping in an old audio card try using the motherboard audio if they were using an sound card. I had one motherboard that had the audio causes stuttering problem, and I installed an old SoundBlaster audio card which cured the problem. My current motherboard has built-in ICH5 audio and I haven't had any problems with it.

Does > ./configure relate to a kernel recompile? No ./configure relates to a MythTV recompile. The steps are: ./configure [configure options] qmake make su [type root password] make install There are more directions in the docs at http://www.mythtv.org If you can wait, I would guess the next release (0.19) will come before the new year. But it most likely will not be compiled specifically for you CPU, which you may need to get HDTV working. It only adds about 10 to 25% to the speed at which MythTV runs, depending on the CPU. But that may make the difference between stuttering and not stuttering. > I've installed almost everything from scratch using yum and I would > hate to go manual unless absolutely necessary.

There is no need to modify the kernel, but you will most likely need to uninstall the MythTV installed by yum, so that there are no conflicts. > On that point, is there a listing anywhere of sound and display video > cards that are known to work with myth and the HD3000, and hopefully > the playback settings in myth to use? No, not really. If you search the archives some cards and motherboard audio that don't work well are mentioned. For display cards, nVidia cards work pretty well, just not in XvMC mode with 1080i video. I use one in XVideo mode everyday without problems (though I need to use the 6629 drivers, rather than newer drivers, for it to use my 1920x1200 LCD at full resolution.) -- Daniel
