I have exactly the same setup working so maybe I can help. Well, nearly
the same, anyway. I have a Freestyle, not a true 250, but close enough.
First, with regards to tuners, my ATI TV Wonder has a Temic 4036 FY5, which
is actually tuner type 8. However, I *think* that model tuner is
more-or-less Phillips compatible. If so, then you can get away with the
standard tuner invocation without tuner incompatibility problems. However,
if you do experience tuner problems, you will need to patch the ivtv driver
to accept tuner type as an argument. I mention that because that is how
I'm running and my current modules.conf incantation won't work properly
without the patch. The ivtv tuner patch, if you need it, is mentioned here:
http://www.poptix.net/ivtv/Aug-2003/msg00218.html
With that said, here is the relevant sections of my modules.conf:
___________________________________________
alias char-major-81 videodev
alias char-major-81-0 ivtv
options ivtv debug=1 tuner=2
options msp3400 once=1 simple=1
add below ivtv tuner
add above ivtv msp3400 saa7115
#options tuner type=2
#add above ivtv msp3400 saa7115 tuner
alias char-major-81-1 bttv
options bttv card=63 radio=0 tuner=8 pll=0 bttv_verbose=2 bttv_debug=0
options tvmixer debug=1 devnr=1
options btaudio analog=0 debug=2
add above bttv msp3400 btaudio
___________________________________________
Without the ivtv tuner patch applied, delete or comment out the four lines
below the ivtv alias and uncomment the last two lines of that section.
For audio, I don't use the patch cable, I use btaudio instead. If you wish
to do so, depending on your distribution, you may have to create additional
/dev/dsp and /dev/mixer devices (I did). If so, see here:
http://lloyd.dyndns.org/index.php?Btaudio%20installation
To complete the btaudio installation, next setup the mixer, which is distro
dependent. I'm running RH9 w/ OSS (not ALSA); all I had to do was go to
the KDE mixer and use the new Brooktree tab that automagically appeared.
Next, run the backend setup. For video, the ivtv card will be /dev/video0
and the bttv card will be /dev/video1. For audio, the ivtv input should be
/dev/dsp1 and the btaudio input s/b /dev/dsp2. The output is still /dev/dsp.
Finally, (re)start the backend and you should be in business!
I hope this helps. Good luck!
