<pre class="ydp1316386fyiv0176228557moz-quote-pre">I've been living with and frustrated by a problem with recordings from

It all started when my local station added a new digital sub-channel.
I know this because my problem started on March 1st and a call to the
station engineer confirmed changes were made to the broadcast signal
early that Sunday morning. He says, "Everything in this encoding scheme
is industry standard, so I wouldn't expect there to be any problem
decoding it with commercial equipment." I'm not technical enough to
determine what has changed that would give mythtv so much trouble.</pre>

<p>It appears the CBS network does a few things differently from
other networks. Not necessarily wrong, just different. With the
local CBS channel and watching via television (not via MythTV) if
the Closed Captioning is set for one of the settings other than
CC1 (I've forgotten which one) a big black box will overlay most
of the screen. This does not occur with any of the other
networks/stations (I tested for 'fun').</p>
<p>Not really of any specific help but I'm wondering if perhaps you
have a Closed Captioning option set? The overlay does not appear
on all CBS programmes.</p>
<p>Also, IIRC VDPAU is for nVidia video cards -- so check correct
and up-to-date. Also found this old note which could explain your
VDPAU issues:</p>

<p>There is a bug with VDPAU rendering. Certain channels in the
USA
are using MPEG2 in a way that overloads VDPAU and causes
pixellation
every few seconds. This is nothing to do with HDHomerun, it
happens
with any type of equipment. The solution is to change to
software
decode and OpenGL Rendering for mpeg2 streams. If you are not
using
VDPAU ignore this email. <br>

<p>I suggest change your profile to one of the OpenGL ones (try
OpenGL Slim) instead of "VDPAU High quality". If that
solves your problem you can customize a profile that uses OpenGL
for
mpeg2 and OpenGL for others, or you can just leave it using
OpenGL
Slim. <br>

<p>Just tried it, but when I played an existing recording, the
audio
played and mythfrontend exited to the desktop...audio continued
to
play until I rebooted. Is there a library I need to install? <br>

<p>Make sure that the Theme Painter is set to opengl2 in
Settings->Appearance. If that does not work you may have a
