can the COMAND play VCD?



Good question, I didn't try it yet but will do so as soon as I get a VCD in my hands (a friend has a collection).
What I can say for sure regarding the 6-CD Changer: it plays all kind of self-burned CD-ROMs, including the CD-R, CD-RW and even copy protected CD-ROMs which usually make a lot of trouble in car music players.
The APS30 in my wife's SLK32 AMG doesn't play copy protected CD-ROMs. Same thing for the COMAND in our ML55.
