kay,
the disadvantage to not having the video up-conversion:
if your monitor accepts component video and you have the up conversion, you can route all your video sources through the receiver and use it to switch sources - as opposed to having to switch both the receiver and the televsion - select dvd on receiver, select video 2 or 3 or 4 on television. With the up conversion, all the video signals are piped out the component out of the receiver and into the component in on the monitor leaving you with one less remote to worry about.
The up-conversion doesn't do anything to enhance the signal, it only converts the exisiting signal to component-like signal - you won't gain any video quality and you won't lose any either.
hope this helps
