Can you open a telnet/ssh window from another terminal and run "top". Watch the %idle value. If this is pegged at 100%, then your problem is that mythtv is taking up too many CPU cycles. On my system, I can record and playback simultaneously with around 10% utilization -- that's 90% idle for clarification.
* what is your processor speed? * what is your video card hardware/driver? * how much system memory do you have? * Do you have a hardware-mpeg-tv-capture? Things to keep in mind: * On slow hardware, e.g. less than 1Ghz processor if you do not have video acceleration, you will likely will not have enough resources to record and playback high quality video. You may need to lower your quality setting to reduce CPU utilization to a level less than 100%. * If you do have video hardware capable of acceleration (mpeg2), then you must configure/compile it to load and work with mythtv playback (for example nvidia-XvMC, or VIA vld-XvMC). --Dave > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:ivtv-devel- > [EMAIL PROTECTED] On Behalf Of Michael Papazoglou > Sent: Wednesday, February 02, 2005 3:11 PM > To: [email protected] > Subject: RE: [ivtv-devel] mythtv stutter with program guide > > > Ok, re-nicing mythfrontend fixed the stutter problem, BUT, now > I can't change channels (using the program guide or typing in > a new channel).
