You need:

The HD3000 card uses the cx88-dvb module. From about the 2.6.13 kernel,
the module has been available as a kernel level module. That is, it is
supplied with the kernel source and the kernel is compiled to make use of
it (either compiled in, or as a loadable module). To use the kernel
module, you need to re-compile your kernel to use the video for linux
modules. (But see below)
Both modules/drivers use a sub-module called tveeprom. These used to be
quite different and completely incompatible. From about October of this
year (and ivtv .40 or so) there has been an effective merger. The ivtv
modules will happliy use the kernel version tveeprom so that the
modprobe.conf line alias tveeprom tveeprom_ivtv can be commented out. This
makes the ivtv driver use the kernel version tveeprom. Then both hardware
cards use the same base module. You get errors if it is the other way
round. If necessary, the ivtv driver can be explicitly told to use the
tveeprom_ivtv driver.
If you just have a PVR card, then use the ivtv drivers AND leave in the
alias line, so that the ivtv driver looks to the tveeprom_ivtv module. You
may not have a tveeprom module otherwise presuming you have not recompiled
the kernel. Note, the you may not actually need to recompile the kernel to
get the kernel version module: if you do a yum update or equivalent which
[snip]
If it is included with the kernel, then the kernel version cx88-dvb module
will be loaded on boot. The process appears not to need any modprobe.conf
entry, but it does need to be told which driver to use so you can get ntsc
(the cx8800 driver) or atsc/qam (the cx88-dvb driver)
I just migrated to fedroa core 4 from mandrake, and I'm a little
confused. I have a PVR-250 and a HD3000. Booting up, it does seem to
find the cx8800 drivers, but like you mentioned, it doesn't load the
cx88-dvb driver. My questions are:
1) How do I tell it to load the cx88-dvb driver at boot?
2) Do I still need to mess with the tveeprom conflicts you described if
I'm using FC4?
Right now my modprobe.conf has these three lines, the second two
commented out (per your instructions I believe):
alias char-major-81 ivtv
#alias tveeprom tveeprom-ivtv
#alias msp3400 msp3400-ivtv
What should I add to get both card working at boot?
Thanks for the help!
