RGB to Component or VGA into Plasma?

[MarkE19]

Ok, so now I finaly make up my mind to get the RGB to VGA converter for my plasma. But then they go and release the RGB to Component.
So the question now is which one?

DVD => Amp => Plasma - Component
VHS => TiVo => Plasma - ?????

If I go component then I will need to go via amp (Denon 3802) and use that to switch between both

OR

If I go VGA then I lose some of the formats ie JUST (and quality?)

HELP!
