[vdr] analogtv, tt s-2300 ff-dvb card and blue faces

I should understand the problem...

the problem is in player-analogtv.c

there is a multiplier of 1927,5 that is ok for bttv, while for saa7134
is different.

This should be patched by adding a dynamic multiplier by reading min/max
value in a similar way like "list_controls" in v4l2-ctl.cpp

There is a maintainer for this plugin that may write a patch?
