The LiveTV stuttering during tv guide got much better almost unnoticeable after I did the mysql optimization stuff. See the mailing thread "Performance MySQL on RAM".<div><br></div><div><div class="gmail_quote">

I'm working on wife factor here.. Live TV does work, with a couple<br>
sub-second pauses here and there, but wife acceptable. The problems I'm<br>
having is while watching liveTV, and I bring up the EPG, the >>smaller TV<br>
picture in the corner will stutter. A couple seconds after bringing up the<br>
guide, it will be fine. Then, after each up/down arrow press to browse the<br>
guide will result in the same stutter, level >>out, stutter, level out,<br>
stutter, level out, etc. It works, but is very annoying.<br>
<br>
This happens on both frontends: (core2duo/NV G210 and Nvidia ION -- both<br>
using vdpau). -- HDHR Prime directly connected to backend. Tried both .25<br>
and .26. I did NOT have this problem on .24. >>Happens on any VDPAU<br>
profile.. happens on any content (1080i, standard-def (which actually is<br>
worse believe it or not)).<br>
<br>
Does anybody else see this, and if so, do you just deal with it?<br>
<br>

This is not much help but I'm having the same issue too. 0.24 was fine<br>
but on 0.26 every time I press the mouse while the EPG is up the picture<br>
stutters. I kind of just deal with it but it's got to the stage >where I'm<br>
contemplating going back to 0.24 because it's so annoying.<br>

In 0.25, apparently code was changed so that every time you jump to a new<br>
channel (you'll notice there is no stutter if you scroll horizontally across<br>
the time), some stuff including a sql query is done to determine if the<br>
channel you just navigated to would be tunable (i.e. it doesn't have a<br>
scheduled recording with new free tuners, etc). The "stuff" that happens<br>
causes the stutter while it processes. I agree, it's annoying, but<br>
apparently necessary.<br>

I agree that it does more "work" when moving channel to channel in the<br>
guide, but I can't believe that it's so much as to cause the video to get<br>
starved for resources.. the CPU's are only at 5%. The network might get<br>
saturated for the SQL queries, as it is streaming the video from the BE and<br>
the mysql engine is on that same backend. I'll check that. Has anybody<br>
tried jumbo frames (MTU 9000)? Good/bad/no difference?<br>

All I can tell you is that was the explanation that I was given by<br>
those "in the know" when I raised the issue when it appeared in 0.25.<br>
Since I have no reason to doubt it, and it made sense (though<br>
admittedly my first, unspoken thought was "then there must be a better<br>
way to do it"), I never pursued it any further. TBH, sadly Live TV<br>
issues do not get much love (other than being told you're doing it<br>
wrong if you're using Live TV, so avoid the issues by doing it<br>
"right") ...<br>

Funny -- Almost sounds like when I was told "I was holding it wrong" by Apple & the iPhone4 debacle. It's too bad though -- there are some of us "old-timers" which still like to channel surf!<br>
