[mythtv-users] PVR-350 on FC6 black screen on playback

[Fred Firestine]

So, do you or anyone else have any idea why this isn't option isn't
being used? Here is the section from modprobe.conf:

alias char-major-81 videodev
alias char-major-81-0 ivtv
alias char-major-81-1 ivtv
options ivtv-fb osd_compat=1
install ivtv /sbin/modprobe saa7127; /sbin/modprobe cx25840;
/sbin/modprobe wm8775; /sbin/modprobe --ignore-install ivtv;
/sbin/modprobe ivtv-fb

Is there something wrong with my syntax? Any other way to send this
option to ivtv-fb? I really don't want to go back to Fedora Core 4;
but I am not encouraged by all the posts I have seen about this in my
research this week.
