As I mentioned in your other thread, you may have problems with moire as others have had problems with the Sony 10HT which uses the same chips. I don't know if it will affect your particular setup, there is (of course) only one way to tell, you must see for yourself. You can eliminate the moire problem with a Cygnus IMX depixilating lens (or depixilizing... I can never remember), but that is a $900 option, it will greatly reduce your screen door though.
It really depends on which particular digital projector you are planning to get, as I mentioned above only the 10HT's, PLV-60's, and one case of the LT150 have problems.
