Similar to your HT system, my projector is a Runco Q-750D connected to an Integra DHC-80.2; My blu-ray player is a Panasonic which is set for 24p output and i haven't had any HDMI synching issues.
However, when i first got my Q-750D i had a huge amount of problems trying to get a HDMI connection to lock on properly between the A/V processor and the projector, to the point that i had to bring the external processor box for repair/exchange to the nearest authorized Runco repair facility after a lot of discussion with the dealer and the repair technician, who told me that he would ship it back to Runco, as that apparently is the company's policy.
When i got my new external processor box and seeing that it exhibited the same problem i decided on a whim to go to the service menu and do a full system re-set, making sure that all HDMI cable connections were in place, and all my problems disappeared permanently ! There wasn't anything wrong with either one of the external processor boxes and i realized that both dealer and local Runco repair facility in MA failed miserably by not instructing customers experiencing connection problems to ALWAYS do a full system re-set after cabling and before calibration.
I would recommend you try doing the same; Just write down your calibration settings before doing system re-set so that you can re-enter them afterwards, and in case you don't have the six digit access code for SERVICE ~ CALIBRATION of the Q-750D, here it is ;
click ENTER once - click RIGHT twice - click LEFT twice - click ENTER once.
Scroll down past CALIBRATION to SERVICE and select SYSTEM RE-SET, which takes less than one minute; Hopefully that will help fix your HDMI "handshake issues" just as it did in my situation.
