I've got MCE 2005, although I've never really used it much as it wasn't really worth the hassle. However I've just ordered a TV tuner (family don't want me hogging the TV during the World Cup - plus I want to record the matches I miss at work), so I thought I'd have a go at setting it up. Problem - any video file I try to open in it, I'll get a "Video Error - files needed to display video are not installed or not working correctly" message. It also doesn't play DVDs. I've tried looking at Microsoft's site, but support there is usually along these lines: "Q. I cannot display video. A. Windows MCE is obviously flawless. You are to blame and we have no intention of helping in any way". I'm also just using the onboard graphics on my Shuttle SS56Gv3, if that's of any consequence.
