[mythtv-users] How to force ivtv.o to initialize the correct card?

[Steven Schaefer]

How can I load ivtv.o and force it to initialize my Hauppauge WinTV PVR-350 
card?

I have an existing PixelView PlayTV Pro (BTTV based, PCI tuner) card, which 
I use with the program "motion". Last night I got the chance to open up the 
computer and pulled out the BTTV based card. After starting up, the ivtv.o 
module successfully found and loaded the Hauppauge PVR-350.

(some hopefully useful 'lspci' output)

If I have the bttv modules loaded I get the following errors when 
attempting to load ivtv.o,

/lib/modules/2.4.26/kernel/drivers/media/video/ivtv.o: init_module: No such 
device
/lib/modules/2.4.26/kernel/drivers/media/video/ivtv.o: Hint: insmod errors 
can be caused by incorrect module parameters, including invalid IO or IRQ 
parameters.
       You may find more information in syslog or the output from dmesg
/lib/modules/2.4.26/kernel/drivers/media/video/ivtv.o: insmod 
/lib/modules/2.4.26/kernel/drivers/media/video/ivtv.o failed

or if I unload all bttv drivers before trying to load the ivtv related 
modules, when I attempt to load ivtv.o the system locks up and I have to 
reboot.

I'm running Slackware 10 on an Intel Pentium III  1 GHz, 512 MB.
My kernel is 2.4.26 with V4L2 patch (20_v4l2-2.4.26.diff.gz) applied.
