I subscribe to -hackers, not -multimedia so please cc me.
I've made up a basic man page for the bktr driver. If anyone has any
changes, please let me know. I installed my bt848 card with no
problem, but I've not fiddled with the driver beyond that.
I was thinking that it would be a good idea to move
/usr/share/examples/meteor to /usr/share/examples/video/meteor (or something..).
It would be a good idea to include a sample prg for the bktr
driver then. I hacked one of the meteor examples to work ( in a
web cam capacity), but I'd bet somebody else out there has a better
version. I also set it up to change my X background every 10 min to a
picture from one of the television channels with a shell script.
fxtv is very cool btw.

.Em Brooktree Bt848 Video Capture Chip.
.Pp
Specifically the following cards work:
.br
.Em Hauppage Wincast TV
.br
.Em STB TV PCI Television Tuner
.br
.Em Miro PC TV
.br
.Em Intel Smart Video Recorder III

.Pp
.Em options "BROOKTREE_ALLOC_PAGES=xxx"
specifies the number of contiguous pages to allocate when successfully
probed. The default number of pages allocated by the kernel is 216.
This means that there are (216*4096) bytes available for use.
