[linux-dvb] Support for rotors?

I also have a SG2100 motor and know of the 'lockup' behaviour your'e
talking about. Check your cabling - my SG2100 only does that when I
switch cables with the power turned on, and while connecting the
cable, the voltage would fluctuate up and down a little bit - this
seems to confuse the motor and it doesn't respond to anything until
you remove power for 30 seconds or a minute. If this happens without
you moving any cables around, I'd check your ends - you could have one
strand of shield shorting occasionaly to the center conductor or
something.
