It looks like we've got a good set of answers here - the short answer is an HDMI/DVI cable (simple adapters are also available, but in some cases you will have the problem of the HDMI connector being pulled loose by the weight of the DVI connector so I recommend a cable like the PDH ) to handle the video (all the way up to 1080p from Blu-ray) without any compromise. For audio, it's going to depend on the source component in question. If you are talking about any existing source component, a traditional digital audio cable (coaxial or optical) will handle the audio exactly the same as HDMI would. HD-DVD and Blu-ray offer some new audio formats that nearly all early adopters will be resorting to a mess of eight analog audio cables to transfer from player to receiver or processor; coaxial and optical digital will carry down-mixed DD 5.1 or DTS 5.1. Seriously, the 990's approach to this problematic issue is very nearly the best you can find, and doubly so in its price range.
