Have a look at the quick quide here - It seems to be the most detailed of the ones listed there. Look at page 20 and then thereafter:
Just doing a quick scan through the pdf indicates there may be some limitations with HDMI(DVI) but the aforementioned page 20 states:
"Using an HDMI Cable for an HD connection (up to 1080p, HD digital signals)
For the best quality HD picture, we recommend using an HDMI connection.
Use with DVD players, Blu-ray players, HD cable boxes, and HD Set-Top-Box satellite receivers." and it then shows a diagram with such a device connecting to any of the 3 HDMI inputs.
Edit: I did a more detailed search through the pdf and I actually did not see any restrictions mentioned for HDMI IN 1 (DVI)
