I just acquired an Ampro 3300. The manual says that it has an HDTV mode. Code 91. When I enter it, it says "bad code". Does this projector have the ability to be put in 16X9 mode. Also, it seems that I have black bands(almost looks like macro vision played through a VCR) on some HD stations. I have a DTC100 and all 540P signals seem to work perfectly. Thanks for any help.
