[mythtv-users] Help with Pixelview BT878 card (unknown) andKnoppmyth

Tue Nov 30 19:54:25 UTC 2004

This is what I used to use in modprobe.conf when I used a pixelview card. I
use PAL so you might need to go through
Documentation/video4linux/CARDLIST.tuner in the kernel source to find an
equivalent NTSC tuner.

options bttv radio=1 card=37 pll=1

options tuner type=5 pal=b debug=1

andKnoppmyth

Linux newbieish here - Ive had to work with redhat just enough to get a few
linux-only things going, so I can just klutz my way around. 

I have a machine Im testing out knoppmyth on, and so far so good. Everything
works but live tv/recording. I have a cheapie Pixelview card I picked up,
and Im only able to get "snow" on the top 1/8th of the screen, which fades
quickly to solid green for the bottom 7/8th. 

I've read the list and searched all I can find, and I believe Im not getting
the correct tuner type set. Im not sure where/how to change this in
Knoppmyth tho, as it seems different than other distros. I'm also not sure
how to tell what modules I have loaded and/or need to load for this to work
correctly.

Here's the output from lsmod:

and a look at the relevant section of dmesg:

Any help at all is appreciated, Im SOooooo close, and REALLY want to get
this working. 

Thanks in advance-
