When diving into the hidef playback and upgrading your equipment, make sure you don't get caught in the marketting game manufacturers are playing.
You don't need more than one video processors. Today you can find Reon/Gennum/Realta/HQV/Farodja advertised in players, receivers, TVs and projectors. And you pay quite a premium for them: just compare entry level and top of the line HD DVD players.
Decide what your setup will be: how many playback devices (HD, BD, PS3, XBox, etc.). Pick just one competent video processor. If you have just one player, let the player do it. Don't buy a projector with those capabilities. If you have two - let the projector do it (and save money on players, buy the cheaper ones). If you have more than two - let the receiver do it and buy a cheap player and projector.
CE manufacturers will double- and tripple-dip with their marketting (that is 99% of the time nothing but crap you don't need, just look at the HDMI 1.3 - that isn't even in their final stage jet, only 1.3a at the moment) if you are not careful.
