Hauppauge PVR-250 with unknown tuner

[Michael Lea]

I'm trying to make a Hauppauge WinTV PVR-250 work with FreeBSD 5.2.1.
I've compiled the drivers that John Wehl posted to the list in March,
but when I "kldload cxm", I get this on the console:

cxm0: <Conexant iTVC16 MPEG Coder> mem 0xec000000-0xefffffff irq 10 at
device 16.0 on pci0
cxm_iic0: <Conexant iTVC15 / iTVC16 I2C controller> on cxm0
iicbb0: <I2C bit-banging driver> on cxm_iic0
iicbus0: <Philips I2C bus> on iicbb0 master-only
cxm0: unknown tuner code 0x52
cxm0: could not initialize tuner
iicbus0: detached
iicbb0: detached
cxm_iic0: detached
device_probe_and_attach: cxm0 attach returned 6

The sticker on the tuner says "NTSC / NTSC-J   32032   Rev B182".

Google turned up a similar problem to mine on the Linux ivtv list...
it looks like my tuner is an LG TAPC-H791F (although I haven't yet
looked under the Hauppauge sticker to confirm this). I tried adding
the new tuner to John's drivers using the Linux drivers as a model.
This is the bit I added to cxm_tuner.c (I also added appropriate bits
to cxm.h & cxm_eeprom.c):

        { "LG Innotek TAPC-H791F", 55250, 801250,
                { { 450000, { 0x8e, 0x30 } },
                  { 170000, { 0x8e, 0x90 } },
                  { 48250, { 0x8e, 0xa0 } } },
                0, 0,
                { 0, { 0x00, 0x00 } },
                { &us_air_channels, &us_cable_channels } }

This got the driver to load properly, but now I get these errors:

# setchannel -t 2
ioctl( tfd, METEORSINPUT ) failed.: Invalid argument
ioctl( tfd, TVTUNER_SETCHNL ) failed.: Invalid argument
# cat /dev/cxm0 >tmp.mpg
cat: /dev/cxm0: Device not configured

Any suggestions? Thanks in advance.
