Short answer is that I don't know.

Longer answer is that I think that the Blue Ray and other is supposed to transmit (via HDMI, I believe) a 1080P signal. My SXRD will only receive 1080I or 720P via the HDMI port. The Sony takes this signal and then converts it to 1080P.

I suspect that you would be able to setup the Blue Ray devices to transmit at other than 1080P. If so, it would not be an issue.
