I get the same thing.  Recordings and 
"cat /dev/video > tst.mpg ; mplayer tst.mpg" work but 
"Watch TV" from mythtv menu doesn't.  However, it's at
the bottom of my priority list since I never use "Live
TV" 
(I find that the picture quality of "Live TV" isn't as
good as live tv).
That being said, this might help:

Everything was working fine before, but then I mucked
up
something else unrelated so I kept the xfs data
partition and
formatted/installed root/boot with FC3.  Here's my
configs:

Hardware:
----------
Athlon XP1800
ECS K7S5A MB
AverMedia M179 MPEG encoder
nVidia NV17 (GF4 MX440)
monolithic front/back end

Before:
------
FC2
Kernel 2.6.9 (don't remember the rest)
Myth 0.17 atrpms from late Feb
nvidia-graphics6629

After:
-----
FC3
kernel 2.6.10-1.770_14.rhfc3.at
mythtv-0.17-97.rhfc3.at
nvidia-graphics7167-1.0_7167-67.rhfc3.at
ivtv-0.1.10-49.2_pre2_ck100zz.rhfc3.at

Also, I had to disable RenderAccel, otherwise X would
lockup
after starting myth.  ivtv 0.2 would load but wouldn't
give me
/dev/video0 (don't remember the dmesg errs offhand). 
The
ringbuffer is on the xfs data partition that didn't
get touched
during the upgrade.  The entire sql db was
saved/restored
for the upgrade.

All in all, I think it was a huge mistake to
"upgrade".  One
of these days, I'll toss a DVD burner in that box and
partimage root/boot to an RW disc before I muck things
up.

P.S.  This is what my backend log says.  The null
string looks
suspect.
