Looks like the DVDO HD+ is a very cool piece of kit, but I was wondering whether or not it would make any sense for me to get one considering what I've already got. Display is a Pioneer 504HDE, fed by a Meridian G91. The G91 takes Sky, TiVo, and occasionally console inputs and converts them to 720p (naturally also converts DVD's to 720p) then feeds the 504's tuner box via HDMI. Would I get a noticeable improvement if I got an HD+ and used that to do all the switching and converting, rather than using the G91? Also, can the HD+ drive the 504HDE in its native resolution, or would I be stuck with 720p due to the fact that it goes via the tuner box?
