I have on old TV card that was handed to me for free (no box,
manuals etc)
The card show's up under lspci like so:
................................................................................
00:08.0 Multimedia video controller: Brooktree Corporation Bt848 TV with DMA push (rev 12)
Flags: bus master, medium devsel, latency 80, IRQ 10
Memory at ec004000 (32-bit, prefetchable) [size=4K]
................................................................................
I studied the bttv howto and made this simple script to load modules
for the card.
................................................................................
tuner=$1
card=$2

rmmod msp3400 2>/dev/null

#modprobe msp3400
modprobe bttv card=$card radio=0 pll=0 bttv_debug=1 bttv_verbose=2
v4l-conf -b16
sync
................................................................................
This will run with no complaints and produce some noice in
/var/log/messages

Then I run xawtv the picture come up clear and nice but it's black and
white. No colors.
I've tried all diffrent tuner types when loading the the tuner
module. I've tried all diffrent card types when loading the bttv
module. I've tried all different norm settings in .xawtv.
The bttv mini HOWTO says
howto> Otherwise, open the case and install the card in an
howto> available slot. Pick one that supports PCI bus transfers
howto> and PCI bus mastering, if your mainboard is picky about
howto> this (see your mainboard's manual). You will want this for
howto> overlay mode.
I have no manual for my motherboard (Tekram P6BX-An) and don't know
what PCI bus mastering is or if it's relevant to my problem. Is it?
Could I possibly benefit from trying the card in all PCI slots?
