Hi Chris,
There appears to be an HDMI to DVI conversion problem. I personally don't have technical background in this subject, but here's a thread that touches on the subject.
Toshiba XA2 - Problems Only
It is believed that when connected via HDMI to DVI the HD-XA2 behaves like the three other Toshiba players and sends PC RGB levels to the projector instead of video levels.
I don't know whether this issue is technically a "Black Crush" issue as stated by videonut in the thread, but I agree with his observations that it seems that even though the HD-XA2 has picture controls to permit adjustments in Contrast and Brightness, it is not possible to adjust both controls to their proper settings. I can get the Black Levels correct, but I can't get the White Levels correct, the whites are crushed. I used both an upconverted standard definition Avia calibration disc, and the video test signal on the French release of Total Recall. (The European releases of Studio Canal titles have an HD video test signal for setting Contrast and Brightness.)
Note:
I have an InFocus projector which is know to have accurate calibrations "out of the box". However, I should point out that it has not been professionally calibrated. Although the lack of a professional calibration may require taking my observations with a "grain of salt", nevertheless, it is important to note that the Contrast and Brightness settings are significantly different via component video versus HDMI to DVI. The fact that the PC RGB level problem isn't supposed to effect component video means that this observation bolsters the contention that there is a problem with the HDMI to DVI video.
