[mythtv-users] X Output on PVR-350

Well, the xrandr support is important since it allows the access to  
the RandR extension in X.  From the man page, the first line of the  
Description is "Xrandr is used to set the screen size, orientation   
and/or  reflection."  My only guess on the cause of the problem is  
that your current version of X doesn't have the randr extension.   
Here is the info on my machine querying xorg-x11 package:

--[root at pvr mythtv]# rpm -q xorg-x11
--xorg-x11-6.8.2-37.FC4.49.2_4.rhfc4.at
--[root at pvr mythtv]# rpm -q xorg-x11 --list | grep xrandr
--/usr/X11R6/bin/xrandr
--/usr/X11R6/man/man1/xrandr.1x.gz
--[root at pvr mythtv]# which xrandr
--/usr/X11R6/bin/xrandr
--[root at pvr mythtv]#


If your output to the above commands is different, you might want to  
do an update - and make sure you followed all the instructions in:
http://wilsonet.com/mythtv/fcmyth.php, sections "5. Get your system  
up-to-date" and "6. Configure 3rd-party package repositories"

If this doesn't work, please send the output from the above commands,  
your xorg.conf file and your dmesg output.
