The most likely solution is to use remote-control of whatever
(the laptop, the DVD player, etc.) Sending video over an audio
pair may be OK for low-res security cameras, but not for the
kind of video you want to project on a big screen.

This is not a typical solution because it is likely not very often
successfull.

VGA *is* component. Typically five signals, Red, Green,
and Blue video, plus Horizontal and Vertical sync.

Sending video over an audio pair may work, but you would
need 4-5 pair to send VGA is you want any kind of quality
out the other end. At least one for each R,G,B video signal.

I think you would be far better off with one of the solutions
that use Cat5 network cable than trying to use the audio
snake. Not to mention the crosstalk video "buzz" you may
get in the mic lines, etc.
