[mythtv-users] My first attempt at PVR-350 TV-out "howto" (very
LONG)

try a /sbin/depmod -a without the uname -r
When this happens, I backout, delete the 3 files and make, make install
again.
Did you compile against the right kernel source?
I know there was a bug with the makefile and the uname -r in the first
line. There was a patch submitted on the ivtv mail list today, or just
put in the path to your source tree.
Cheers???
