I'm wondering if there are any known problems using a geforce4 card
and a winfast tv2000, nVidia's X driver, and bttv. I simply cannot
get them to work together.
I have a 64Mb geforce4 and a winfast tv2000. I was having these
problems with a pIII650/1Gb, abd the problem is persisting on an
athlon 2100+ with 1Gb. In the past I have had the winfast card
working with a 16Mb TNT card and an old version of the nvidia
driver.
The radio tuner works fine (with /usr/bin/radio from xawtv). I
have a dvd player on this box: mplayer, ogle and xine all work
well, same for 3D graphics (games etc).
This is what happens:
$ v4l-conf
v4l-conf: using X11 display :0
dga: version 2.0
mode: 1600x1200, depth=16, bpp=16, bpl=3584, base=0xd8000000
can't open /dev/video0: Cannot allocate memory
$ xawtv
This is xawtv-3.73, running on Linux/i686 (2.4.18-27.7.x)
can't open /dev/video0: Cannot allocate memory

v4l-conf had some trouble, trying to continue anyway

$ tail /var/log/messages | grep kernel

Mar 20 19:32:11 linuxbox kernel: bttv: vmalloc_32(4259840) failed
Why can't the memory be allocated by the driver?
More details are below.
