Dr.Dish: The colorsystem in up- and downlink is mostly identical. To receive 
all the different color-modes, you have to use a multi-color tv. The 
satellite-receiver does not convert any signal from one the other system. 
The build in modulator usually is made for the system of a specific country. 
To avoid incompatibelity, just connect the tv-set to the sat-receiver with 
the SCART- or RCA connectors.
The noise of a motor can be cut down by connecting a power-resistor in line 
with one of the two 36V-motor-cables. The motor runs slower, but also much 
more silent. Try different values until the motor runs smoothly.
