Thanks for those questions.  I see from the log for mythfrontend (see the log 
at the end) that it seems it cannot find Xv.  I am not sure what this is, but 
after google-ing some I found that I can run xvinfo to get some information.  
This is what I got:

======================
X-Video Extension version 2.2
screen #0
 no adaptors present
======================

From my google-ing it seems I get this when I do NOT tell Myth to use the 
pvr-350 hardware for playback.  However, I have checked this many times (and 
I just checked again before sending this out).  I have "Use the PVR-350's TV 
out / MPEG decoder" checked and the ¨Video device for the PVR-350 MPEG 
decoder:" is set to /dev/video16.  Farther down I have "Program Guide Alpha:" 
is 164.

I am not sure.  I do not have mplayer installed (I think I uninstalled it by 
mistake at one point and urpmi wants to install the wrong liblirc0.lib, so I 
have to download/compile it... have not gotten to it yet).  I scheduled a 
recording o Myth and I see the drive light going on every so often, so I 
assume it is recording.

At one point I did run all these tests and I was able to see just fine.  As a 
matter of fact, I remember I did something like
dd if=/dev/video0 of=/dev/video16
and I was able to see tv just fine.  The problem seems to be within Myth.

Thanks!!

You likely won't get any video.

* Couldn't find Xv support, falling back to non-Xv mode.
* MythTV performance will be much slower since color

* Consider upgrading your video card or X server if
