I've been silently reading the different posts and I figure that I should post to let you know that I'm still here :-)

Regarding the whole "I have the info but I can not give it to you" issue, I kind of understand the persons that are telling us that if they really say this out of frustration.
On the other hand, despite any "super-duper" system that Broadcome could have to protect the documents, and as much as they could change words and shuffle them around, I really doubt that they will dear touch the sample code (at most the *could* change the name of some variables).
And even a plain sample code would be really helpful ... and if one of us were to get a copy of it, it would not be hard to "rewrite it" so it's not traceable ... but I don't count on that happening anytime soon.

For the rest of the post, I learned that I had not done my homework as good as I believed ...
I knew about the Snazzi capture cards and That's why I was surprised that there is not a lot more info available (I only found a partial code for a driver), still, I was planning to use the little info I got for this cards as my starting point.

On the other hand, I did not knew about the microkernel needing to be changed to start with, nor did I knew that the KFIR and KFIR-II had the same registers ... something interesting to investigate a further.

thanks a lot for the info ...
