Wintv-1250 - EEPROM decoding - V4L DVB

[Michel Dansereau <Michel.Dansereau@videotron.ca>]

Hi,
    I was trying to get the WINTV  HVR1250 analog interface to work.
    So far I kludged the cx23885-cards.c file to enable the decoding of 
the eeprom.
    The required offset in the eeprom is 0xC0

    I did not get very for after that.

    FYI the firmware suggested by development site sees wrong ... The 
encoder firmware especially. I think that the following profile is 
required by the code.
    The code requiresfirmware with these sizes (these are from the 
hauppage distro.

I hope this helps.
