So I read on the MythTV PVR-350 WIKI that I could add options for the
ivtv module to use instead of the defaults for the buffers. Well I
couldn't find the file that the wiki tells me to add the options to
(/etc/mythtv/modules/ivtv) but I do have a /etc/modprobe.conf file that
has other options for lirc module and for my serial irblaster module. I
added the following there:
options ivtv yuv_buffers=32 mpg_buffers=16 vbi_buffers=16 pcm_buffers=16
dec_osd_buffers=2
but when I restart the dmesg output shows this:
ivtv: Unknown parameter `yuv_buffers'
so then I figured I didn't even need the yuv_buffers to be set since I
don't use /dev/video32 so I removed that from the line and left
everything else. Another restart and now I get this error:
ivtv: Unknown parameter `mpg_buffers'
When I leave these options in the modprobe.conf file, my card doesn't
even show up in mythtv and when I issue lsmod | grep ivtv, it's not even
being loaded. Apparently trying those options is preventing the ivtv
module from being loaded.
Obviously I am not understanding something. I read the module.txt
located in /usr/share/doc/ivtv-utils/ and it actually states that all
the options I am trying to use are valid options so can please someone
help me with this issue.
It appears the wiki is out of date for ivtv0.10 stuff. You can
get the latest command line arguments by doing a 'modinfo ivtv'
as root:

Looks like maybe you want enc_mpg_buffers and/or dec_mpg_buffers....
