My mother has always just got a black screen on another channel,
FilmFour, using her freeview set-top-box.
Since it doesn't seem to bother her much, and I am only just starting
to think about TV / MythTV for myself, I only started pondering this
recently but could the cause be poor reception? Her aerial was bought
new for analogue channel 5, but at that time its direction was set by
hand & by eye - I don't think it's been adjusted since. The best we
could get for analogue channel 5 was fuzzy but watchable; all other
freeview channels are fine.
Were you able to watch Filmfour+1 with a previous install of MythTV?
It may be that the drivers for your tuner card released with this
version of the kernel are not so good.
Have you tried viewing the channel using other tools from MythTV?
I believe there are command-line tools for some tuners that allow you
to set the channel; you may then be able to redirect the output into
a file & open it with your favourite mpeg player.
Are you able to watch the same channel using an STB or with the same
tuner card under Windoze?
I don't think a full reinstall is likely the best way to resolve this
