HVR1255 svideo

Hi

I've been trying to get the Svideo input on my HVR-1255 working.  From
the latest code in cx23885-cards.c, it seems that only DVB is
supported.  I have some experience writing Linux Kernel/Drivers so I'm
determined to get this working.

I copied the cx23885_boards[CX23885_BOARD_HAUPPAUGE_HVR1250] settings
and did get the V4L layer connected enough to get a /dev/video0,
albeit with only green video and no picture.  I then realized that was
probably a dumb thing to do (possibly damaging the GPIO), since the
eeprom is clearly different based on what I saw in tveeprom.c.

My question is, am I going down the right path to add this support?
Should I go ahead and install Windows (sigh) and get the output from
RegSpy?  Are there any developer git trees that are focused on this
area?

Regards,
Jon
