It's not so much that it's HD but that it supports the MPEG4 streams that VM is switching all the channels over to eventually. The better codec (H264 I Think) will allow for more content and/or better PQ.
It also has the incidental advantage of a down scaled SCART socket output so I can used my DVD/HDD recorder and the modulator.
We never seem to need to record much content so a TIVO or V6 is of limited interest.
