[vdr] [PATCH] set channel on command line

[Rob Shortt <rob@infointeractive.com>]

Hello,

Here is a little patch for vdr-1.3.11 that allows you to set the channel 
to start on, on the command line.  I find this especially useful for 
testing when brining VDR up and down often.  Some people may also like 
to startup VDR on the same channel all the time as well.

The flags are -C and --channel=, ie: vdr -C50.  I hope someone finds 
this useful and maybe it could be included in VDR by default.  Enjoy. :)

-Rob
