I'm about to take the plunge to upgrade my 5 year old Sharp projector to the Sanyo Z1, probably from AV-Sales or Nexnix as recommended here. Two final questions though. 1. How does it handle 4:3 material? I have a fixed 16:9 screen so what I'd hope is that it can function as a widescreen TV and show the 4:3 image in the center with black borders left and right. Is this the case? 2. I am keeping the ceiling mount from my Sharp (as detaching it from the ceiling will be a difficult job - it had to take 12 Kg!). As the mount is far bigger than the Sanyo, I'm planning on fixing a wooden shelf onto the old supports making my very own shelf mount. The projector would then sit the right way up, about 1 foot from the ceiling. The top of the screen is at this height also, so here is my question - Would the lens-shift (and/or keystone) functions allow me to project onto the screen and get a proper squared image. My old projector would be horribly squewed as it could only project from its lens upwards when upright. Many many thanks for helping me get to this decision so far... Adam.
