Hi I have an Epia box which did something similar. The stuttering was accompanied by load of "prebuffering pause" messages from mythfrontend.
This is what I did to correct the stuttering: 1. Run mythfrontend as root or suid mythfrontend. 2. Run mythfrontend with nice -15 or so. eg "nice -n -15 mythfrontend" Hope this helps.
