Hi Mike, I had a similar problem and was able to help remedy this by launching mythtvfrontend with the following command:
nice -n -15 mythtvfrontend That forces the front end task to run at a very high priority. It will consume only as many cpu cycles as necessary to maintain a smooth image, and then yield the remaining time after it blocks -- at that point other non-realtime requests will be serviced. The database requests and other requests will now get executed at a lower priority which should prevent your video playback from stuttering. That worked for me since I run the backend, frontend, and the database server on the same machine (I have a EPIA-M 1Ghz box). Hope that helps, --Dave > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:ivtv-devel- > [EMAIL PROTECTED] On Behalf Of Michael Papazoglou > Sent: Wednesday, February 02, 2005 1:24 PM > To: [email protected] > Subject: [ivtv-devel] mythtv stutter with program guide > > > Hi - > > When using the ivtv-0.2.0- drivers (i've tried rc3a - rc3e), mythtv > stutters when I bring up the program guide.
