Exposing an input to the kernel demux via userspace doesn't sound like a 
bad idea. It would certainly allow developers to build DVB/ATSC 
applications without having access to live feeds, instead using canned 
loops provided by who-ever.

Any reason why this feature (not necessarily this specific patch) 
couldn't be part of the regular v4l-dvb tree?
