Hermann,

I showed him how to make a patch and suggested that he send it in to the mailing
list for exactly this reason -- because I am not familiar with all the
intricacies of the various saa7134 cards.  I had some issues with his original
patch, and I gave him some critique.  I would not commit the patch for him even
then, because I figured that some other eyes might see other issues.  Yours, for
example.

He did not simply duplicate the code -- his card has the tuner on a different
i2c address.  What do you suggest that he do instead?

His card seems to be dvb-t only, he claims no analog support, but I have trouble
believing that, given that it uses a tda8275 tuner and a saa7131 bridge -- this
bridge has a tda8290 spliced into it.  For sure the card must support analog tv,
but he says there is no radio input, no svideo input and no composite input.

Feel free to make any suggestions, I will not commit any patch if people disagree.

Cheers,

Mike
