Well, for a rollup this release is very dissappointing. Especially as we are now looking at over a year before the next release of Media Centre (rumoured to be built into the Vista Operating System). First off, installing this update hosed our two demo units, and only worked on fresh build systems. We had to rebuild both test units, and reimage after installing this update - just to make sure we could restore them if the worst happened. Added to this, there are a couple of glitches with graphics but nothing major - so far. The biggest plus is the addition of DVB-T radio playback (at frigging last!).
