[mpeg2] Re: kfir and linux 2.4.XX

I doubt the problem you are having is related to any of the i2c components.

I have a highly dprink'd version of the driver that i use when im trying to
figure out that the crap is going on, and where my machine locks up.  If you'd
like, I can send it to you.

Generating a 0 length file is probably due to you telling the SAA7113 to decode
NTSC, but create a PAL datastream (or something like that).  There are 2 format
options that are DIFFERENT due to the definitions in the v4l headers..

I think its like vidinmode=0 vidmode=1 or something similar are the flags you
want to use.

Hey, maybe you can throw some of your muscle around and talk to Broadcomm and
try to get the Kfir API back.  It seems to have dissaparerd, and metzler
donesnt have any leads.
