      <pre class="moz-quote-pre" wrap="">I've been living with and frustrated by a problem with recordings from 
my local CBS broadcast channel.

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>
    </blockquote>
    <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>
