[mythtv-users] X-screensize do not match tv-screen-size

By default, MythTV expects to use 800x600, however, as
your log shows, the PVR-350 is only capable of 720x576
(in PAL mode, 720x480 in NTSC), at least with the
modelines that you have specified.

You could try changing the modelines and see if you
get output other than 720x576, but I'm not so sure
that would work (myself, I haven't tried).

Use the options within the GUI to change the size of
the MythTV GUI window, TV output will be fine.  Search
the archives for details on how I and others have done
