Connecting direct to Sharp PG-f320w video projector via HDMI (with DVI adapter) presents no problem. Acquisition of a second HDMI source required buying aKramer VS 21HDMI switcher as projector only has 1 HD input. With swich connected between DVR and projector, signal won't go thru. Tried all possible EDID combinations in the switch, but no go. Kramer then informed me their product is only HDMI 1.2 compatible and your DVR is probably version 1.3. They suggest trying to force DVR down to version 1.2 for compatibility but I don't know if this is possible or how to do it if it can be done. Please advise. Juan Moreno
