G'day all,

I've this MiroPCTV card stuck in my machine and thought that it
was time to become adventures and re-activate this gadget.

Not being a kernel hacker I've tried the obvious and got the kernel
to recognized my card - see below.

bktr0 at pci0 dev 18 function 0bktr0: interrupting at irq 9
bktr0: buffer size 3555328, addr 0x409000
bktr: GPIO is 0x00ff07ff
card signature
 00  00  00  00  00  00  00  00  00  00  00  00  03  00  00  00

Miro TV, Temic PAL tuner.

The actual devices were defined as

cr--r--r--  1 root  wheel  65, 0 Oct 17 00:42 /dev/bktr0
cr--r--r--  1 root  wheel  65, 16 Oct 17 00:42 /dev/tuner0

After this, I've built fxtv-1.00 which compiled without problems.
Now, everytime when trying to run this program the following message is
printed to the console:

hotdog# fxtv
mmap of driver buffer failed: Invalid argument

ktrace reveals the following:

345 fxtv     RET   read 32/0x20
345 fxtv     CALL  open(0xefbfd794,0,0xefbfd744)
345 fxtv     NAMI  "/dev/bktr0"
345 fxtv     RET   open 4
345 fxtv     CALL  open(0xefbfd744,0,0x72400)
345 fxtv     NAMI  "/dev/tuner0"
345 fxtv     RET   open 5
345 fxtv     CALL  ioctl(0x5,_IOW('x',0x2e,0x4),0xefbfd724)
345 fxtv     RET   ioctl 0
345 fxtv     CALL  mmap(0,0x1b0000,0x1,0x1,0x4,0,0,0)
345 fxtv     RET   mmap -1 errno 22 Invalid argument
345 fxtv     CALL  __fstat13(0x1,0xefbfd440)
345 fxtv     RET   __fstat13 0
345 fxtv     CALL  break(0xaaffc)
345 fxtv     RET   break 0

Its getting late and I am running out of ideas on how to tackle this
problem. Which strategies can I use to find out whats going wrong
here? 

I apreciate any help and advice on how to continue from here.

Sysinfo: NetBSD-1.4.1-i386, brooktree848.c version 1.85 19990612,
         fxtv-1.00

Many thanks in advance
