[linux-dvb] apps/scan

["Christian Tramnitz" <christian@tramnitz.com>]

Hello,

since I'm using both DVB-T and DVB-C now I had some trouble with the
"scan" tool in apps tree:
It's currently hardcoded to adapter0...


I just copied some stuff from szap so that you can choose at runtime
(with "-a") which card should be scanned.
I also got the selection for frontend (-f) and demux (-d) although I do
not think this makes much sense...

I hope this useful for someone else or maybe Holger will even add this
to the cvs :-)



(diff is against current cvs)
