By chance, I ran into an executable "/usr/bin/mythavtest" and ran it.
It seems to be a light client tuner/renderer and it seem to work fine
tuning and playing all channels. But for some reason the video
renderer on my 'mtthfrontend does not seem to be working.
Thanks

<pre class="moz-quote-pre" wrap="">You can find them in mythfrontend in Setup / Video / Playback and then

You can select from a list and with the right-arrow you can modify the

Your log suggests that it is trying to do playback with XVideo and that is
kind of obsolete.
It could be that this setting for video playback is carried over from an
older installation.

Yes, I think you've got old playback profiles from your previous
mythtv installation. Briefly, I think you need to delete all of your
playback profiles, exit setup, go back into setup and the new
profiles should be recreated. To delete a profile, go to Setup ->
Video -> Playback -> Current Video Playback Profile, then
right arrow brings you to a page where you can mark the profile for
deletion. Rinse and repeat.<br>
<br>
When you have deleted them all, allowed your changes to be saved,
then re-entered Setup -> Video -> Playback, the available
playback profiles should be:<br>
<br>
NVDEC Normal<br>
OpenGL High Quality<br>
OpenGL Normal<br>
OpenGL Slim<br>
V4L2 Codecs<br>
VAAPI Normal<br>
VDPAU Normal<br>
<br>
At least this the list I see on v32. There might be some slight
changes on v33, v34/master, but I think the procedure will give you
playback profiles supported by the version of myth you have
installed.<br>
<br>
Also, if you have more than one frontend, you probably need to
repeat the same procedure, because I'm pretty sure they are stored
per frontend, not per system.<br>
