[mythtv-users] pvr-150 tuner type 47 problem

[Mark Knecht]

Dan,
   Maybe I'm not seeing it but I cannot tell what version of ivtv you
are running. On newer versions of ivtv  no_black_magic is no longer a
valid parameter.

   We have a PVR-150 in a Gentoo-based backend here. We are running
ivtv-0.3.5p from the development donwload site. All we do to run it is
this in /etc/conf.d/local.start

modprobe tveeprom
modprobe ivtv

ivtv will not earlier in the boot sequence for us so sticking it in
loacl.start was acceptable and is working fine. Everything about the
newer drivers seems to be working well for us.

   Hope this helps. If you need more info feel free to write back on
the list or directly.

Cheers,
Mark
