I'm not sure that it's a CPU power issue. I see this on my MythTV system I just set up (Athlon64 3200+, NVidia FX5200 with XvMC, dedicated drive for ringbuf in DMA mode, etc..). I get the prebuffering pause messages sporadically. Sometimes I get stutters on one channel, but not on others. At this point, I'm not really sure what is the trigger for the stuttering. When my video is running smoothly, I can do many other things on the system, without impacting the video. A couple days ago, I had an HD program playing via Live TV, and was ssh'd into the system and compiling the Qt libraries. The video was flawless, no glitches, pauses, etc.. > 2) So I enabled XvMC, which works pretty well. The OSD gets all > garbled and painted wrong but that is preferable to the stutter.

The same thing happened to me. I ended up modifying MythWeb, to add the attributes for xmltvid, mplexid, atscsrcid, etc. Then, I combined the fields into one entry for each channel, with all the necessary data. I also used this to add some channels that my cable system carried without PSIP data, so they were not found in the channel scan. > Thanks > _______________________________________________ > mythtv-users mailing list > [email protected] > http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users > _______________________________________________ mythtv-users mailing list [email protected] http://mythtv.org/cgi-bin/mailman/listinfo/mythtv-users
