Despite of all previously, this is _not_ a place for any closed source to discuss. There is nothing to discuss on that, please stop it. Either try to come back with open source in a new round, or at least don't try to hide what you have. Without all the code and hardware specific stuff _previously_ developed/hacked on v4l-dvb, you don't exist. I still admit, overall, you did a very good job previously, but all others are _not_ just your captives after some clashes. With "unfortunately we're closed source", you deliberately declare, that you have nothing to do with open source at all anymore. ? So, what is the remaining interest for you, except that you can continue easier in userspace, instead of getting a hard block in the kernel, if some enough have enough of your "closed source" ?
