Ken,
don't forget FireWire!

It's similar to DVI connections and is just starting to become popular in home audio/video. It is present in some Apple computer connections. Both it and DVI are pure digital signals. There's debate about which is superior, but I'd lean towards FireWire. DVI will restrict/prohibit copying of digital signals, whereas FireWire will allow it to some degree. Also entire home electronic networking possibilities are endless with FireWire.
