[ATrpms-users] Problems with Latest Mythtv Packages

[John Welch]

Hey Axel,

Just wondering if any compile time options (or anything for that matter)
would have changed in the latest mythtv pacakges (from May 1st) that would
have adversely affected HD playback.  Honestly, I haven't looked into my
problem much; just did a quick search on the ATrpms and Mythtv lists, but
didn't see any similar posts.  Basically, all I can tell you at this point
is that I went to watch some HD recordings last night on my primary
front-end system where I watch HD recordings all the time and I was getting
major stuttering issues.  I'd get a few seconds of normal playback, followed
by a pause, and this repeated over and over throughout the entire recording
(I tried several recordings).  When I looked at my system I found that the
mythtvfrontend and X processes were combining to take up virtually 100% of
the CPU (80+ for the frontend process).  It has been a while since I've even
looked at these numbers on this system because normally it just works, but I
would guess I typically run around 60% CPU usage when doing HD playback.
What's strange is that I'm still trying to put the pieces together, but I
swear I watched HD recording Monday night, and that was after I had put in
the latest packages.  Now that I think back, I remember a little bit of
stuttering, but no where near as bad as last night, when these recordings
were basically unwatchable.  The only other packages I remember updating are
the latest libraw1394 packages that came out on May 3rd.

The reason I ask about the compile options is that prior to the official
release of 0.21 I was running the SVN 0.21 packages from the bleeding repo
for over a year and I had similar HD playback issues with a couple of the
releases, which I think were tied to debugging being turned on in the
packages.  I also seem to remember, and this might be going back to the time
when I was running 0.20 release, where the packages were released one time
without MMX being turned on.
