[mythtv-users] Troubleshooting video problems on my combined FE/BE

[Jerry]

I'm experiencing some video glitches on my FE/BE.  Typically, they occur
when there is a long shot of video where the camera pans an area for ten
seconds or so.  I also see other glitches at other times.  It is connected
to a 2014 Samsung Smart TV by an HDMI cable.  The system is a Core 2 Quad
Q9400 with 8 GB ram, and the OS runs on an SSD drive.  The recordings are
on a 3 TB hard drive.

I have tried switching video playback modes.  I have a GTX 260 card and I
have been trying to use VDPAU Slim.  I have tried Normal as well, and Slim.

I am not seeing these issues on my frontend running on a Core 2 Duo machine
on the wired network.  It has a GTX 9600 card.  I only just installed it
tonight to troubleshoot the problem.

I produced this log with -v playback.  I apologize if it is too much
information, but I was unable to see any problems with the default
logging.  I'd be happy to run it again with different levels of debugging.

I put a GTX 560 Ti in this machine and I still got the same dropping of
frames.  I followed JYA's guide for judder free playback in case it is due
to issues with the refresh rate.  I have all of the standard refresh rates
incorporated into my xorg.conf as per the instructions on the wiki.

Does anyone have any ideas?  A few days ago, I was only a click away from
getting a new video card, but this does not seem to be the problem if my
oldest computer with the slowest video card has no problems with playback.

I am not seeing any spikes in CPU usage during playback.  I do have a
number of other services running at the moment such as Plex, BubbleUPnP
Server and Serviio.  I disabled all but Plex just now and I'm still seeing
the video glitches.

Thanks for any help!
Jerry
