A question: does this driver only do SDR, or does it also 
do 'regular' video and/or radio?

If it does, then how does it switch from one tuner mode to another?

E.g. from ANALOG_TV to RADIO to SDR?

During the Barcelona summit in 2012 we discussed this. See the last two
slides of my presentation:

http://linuxtv.org/downloads/presentations/media_ws_2012_EU/ambiguities2.odp

Basically this proposal was accepted provided that the code to handle tuner
ownership should be shared between DVB and V4L2.

I made an initial attempt for this here:

http://git.linuxtv.org/hverkuil/media_tree.git/shortlog/refs/heads/tuner

I never had the time to continue with it, but it might be useful for rtl2832.

Regards,

	Hans
