My current system;AE900,VP-30,older Pio. elite rcvr.,PS-3,XA-2,DTV HD,5.1 speakers and Carada BW 104"1.85/1 screen .I am remodeling and upgrading my system that I now use zoom for 2.35 movies.My goal is to have a 2.35 setup with prismasonic or panamorph and 1080p projector.My question is can I use my VP-30 for stretch only without degrading my 1080p/24 signals so the projector doesn't have to have that capability?I also have a new Onyko 805 rcvr.and will aquire a 2.35 screen.

The iScan VP30 can not process a 1080p input signal (regardless of the frame rate). For this application you will need an iScan VP50 or VP50PRO, either of which can process a 1080p input signal and apply a 33% vertical stretch (if necessary). The VP50PRO also has a 12V trigger that can be connected to an anamorphic lens with a sled to simplify the use of the lens.

Josh,are you saying that the VP-30 can't pass 1080p unprocessed or bypass? John

What he said is the VP30 can't process 1080p at any frame rate (except for colorspace conversion on the HDMI input). He didn't say it can't pass 1080p unprocessed, which it can do.

Stretching the image, requires that the signal be processed (scaled, to be specific) and the VP30 can not do that with a 1080p input signal (or any input signal that is being passed through). This means that if you have a 16:9source and your lens is not being used, you can pass the signal through the VP30 and life is good. If you are using the lens with a 1080p source and 2.35:1 content, passing the signal through the VP30 will result in an image that is vertically squashed and that does not vertically fill the screen (with massive "black bars" top and bottom) but does fill the width of the 2.35:1 screen. You will have a similar issue if you have a fixed lens application and you are viewing a 1080p source with 16:9 content, except that the image will be stretched horizontally filling the 2.35:1 screen.
