I am lost on this one. I would love it someone could give me some ideas.

My mythtv works well except for the OSD. Whenever the OSD should be showing up on
the screen I get this message in syslog:

ivtv0-osd warning: Size is overflowing the framebuffer 1638400, only 1382400 available

and this one in the X server log:

(EE) IVTVDEV(0): FBIOBLANK: Invalid argument

my ---- fb0 is 1638400 -- vesafb
fb1 is 1382400 -- pvr350 tvout

-- Thanks, Martin
