[vdr] Solution for a rotor

[Norm Dressler]

I have a rotor on the way for my dish so I took a look at the rotor 
plugin.  I noticed the screenshots didn't have commands like up or down 
for the azimuth -- are they in this plugin or  should I be looking to 
another solution? 

Also, what's used to scan the transponder?  Do you have to know what sat 
you are looking at and then enter the transponder freq for it to scan it 
properly?

Thanks for any info --
