I added another 512 MB of RAM for a total of 768 now and do not see any improvement with playback. Top is telling me that no swap space is even being used. Also when I try to playback HDTV, the backend is not recording anything, so recording at the same time is not the problem (yet). I have not done any OS upgrades recently, I just got the HDTV card about a month ago and have always had this issue. I do not believe I have any problems with my xorg.conf since playback works normally with Xine. Are there some compile flags for MythTV that I should/should not be using?<br><br /><hr />Gear up for Halo® 3 and get a $25 Best Buy gift card.
