Just did a little mental backflip and came up with something...<br><br>Reading another thread got me thinking...it hadn't occured to me that Digital != HD, I'd always coupled the two. Not all programming comming through is HD...typically just prime time on major networks (for over the air). Given that all of my KIDS shows come in without a hitch and all of MY shows (which are all prime time major network shows...like Alias, Gray's Anatomy, etc...) are off when played through Myth TV's internal player...
<br><br>Could it be something having to do with HD content? Is there maybe an issue with AC3 sound in my setup? (HD programming comes across with digital/encoded sound where as non HD programs I assume do not?)<br><br>Grasping at straws here...

<div>Wierder yet: I'm not seeing this on PBS. BTW it IS happening on Live TV as well, not nearly as pronounced. When I run MPlayer through MythTV (I believe that's what's used to play back recorded shows by default correct?) I do get the issue, but when I run it OUT of MythTV, I do not. So it's not a function of the player software either (unless MythTV uses it's own media player to playback the MPEG stream, in which case it would be Myth's player that would be the cause of the problem).
<br><br>Did some TOP testing, looks like i'm only running 29% CPU when live TV is playing or when i'm playing back a video through Myth. What I DO notice is that whether i'm running as root, have the bits set in /etc/security/ or whatnot for Real Time scheduling, I STILL don't get a realtime thread. I do have the option checked in Myth TV (use realtime scheduling)...the settting in MythFrontend's setup, main page I think. Could that be an issue (it's the thread's value seems to be 15, which is somewhat higher than most of the rest of the processes, tho I do have several marked as RT, which I assume is Real Time).
<br><br>So, it doesn't look like a function of the hardware, it doesn't look like the function of the software player (mplayer or xine). It's either some kind of delay that myth isn't picking up on that the externals are, or it's something to do inside myth with the way it's syncing up audio.
<br><br>I'm guessing i've come to the end of my rope on this board, but before I go subscribe to the dev list and bother them, i'm looking for any last advice here...<br></div><div><span class="sg"><br>--Douglas Wagner</span>
