Can anyone explain what the difference is between a single link and a dual link DVI cable? I know that they both have the same basic connector, but the dual link has all 24 pins in the connector and the single link has 6 pins missing in the center which results in 18 pins. What does single link mean? What does dual link mean? The DVI output on an 811 receiver requires a DVI-D cable, but it is not specific about whether it should be single or dual link. Will either one work?

Single link uses one set of digital RGB + clock wires, and dual link uses two sets of wires, all in the same cable assembly. The two links are there to provide higher bandwidth. Single link can handle HD resolutions. Most all DVI equipped components are single link.
HDMI is electrically the same as DVI, but can also pass audio over the same wires by time multiplexing it in with the video. You can connect DVI sources to HDMI displays with the appropriate connector adapter (which is purely mechanical). Eventually HDMI will be favored over DVI because the connector is physically smaller and it can eliminate the separate audio wires. Lower cost!
