[mythtv-users] LiveTV stutter while in EPG/Guide

[Matt Piermarini]

I'm working on wife factor here.. Live TV does work, with a couple 
sub-second pauses here and there, but wife acceptable.  The problems I'm 
having is while watching liveTV, and I bring up the EPG, the smaller TV 
picture in the corner will stutter.  A couple seconds after bringing up 
the guide, it will be fine.  Then, after each up/down arrow press to 
browse the guide will result in the same stutter, level out, stutter, 
level out, stutter, level out, etc. It works, but is very annoying.

This happens on both frontends: (core2duo/NV G210 and Nvidia ION -- both 
using vdpau). -- HDHR Prime directly connected to backend. Tried both 
.25 and .26.  I did NOT have this problem on .24. Happens on any VDPAU 
profile.. happens on any content (1080i, standard-def (which actually is 
worse believe it or not)).

Does anybody else see this, and if so, do you just deal with it?

AND SO ON.. It will level out in a couple seconds.. but then after any 
button/keypress while in the guide, it will repeat.

Thanks for ideas,

Matt
