3200MP - Keystoning, Light Path, Ceiling Mount

Hi,


I just received my new 3200MP and I have a couple of questions.   I have not yet spent much time attempting to deal with these yet but I thought I'd at least put them out here ito see if anyone has any helpful information:

1) I'm noticing some oddities when using keystone correction when displaying an HDTV (480i) signal (from my xbox) (via composite input).  The keystone correction works, but it leaves a light gray border around the areas of the image adjusted by the correction.  This is awfully disturbing.  Is this behavior normal or is there something wrong ?  Is there anything that can be done to eliminate it ?  Will this occur for any HDTV signals ?  Note that I did not see this border when I tried an S-video input signal.

2) This is related to (1) above.  Since I'm attempting to use the 3200MP in a psuedo home-theater setting, I want to have it in the rear of the room and somewhat elevated.  It appears that if I put the device any higher then table height (which is too low for my environment), the image is displayed close to the ceiling.  To deal with this, I need to angle it down, which leads to keystoning and the issue I have in (1) above.  Is this behavior normal, or is there just something wrong with my 3200MP ?

3) Would a ceiling mount help me out ?  If the light path is really aimed up when the 3200MP is used normally, then I'm assuming that ceiling mounting it would aim the image down (which is where I want it) since the device would be mounted up-side down.  Hopefully, this would eliminate keystoning issues since the image should be closer to where I need it to be.  What are the mounting options for the ceiling mount and how can cabling be handled ?  Any help would be appreciated.

Thanks,

Chris Lyons
