Just take a look at what cSVDRP::CmdGRAB() does. The actual task is performed
by the call to cDvbApi::PrimaryDvbApi->GrabImage(FileName, Jpeg, Quality, SizeX, SizeY),
which should always work, independent of whether you are viewing a live signal
or replaying a recording.

I haven't given that much thought yet. Most likely I will define lots and lots
of key definitions for the various functions possible, and allow the user to
define which function shall be put on those keys, because whatever definition
I would come up with, there would always be that one user who wants it different...
