The Apple TV would not do DVD. The Mac Mini can be controlled from the Beo 4 witht either Beoport or Lintronic or IRed/IRtrans. So if you like a dedicated media server this could become very nice. Except Beoport(that doesnt support fast scrolling) it is a bit fiddly though, i.e. it will take you some work (and frustration) to get it running.
Apple sells a DVI adapter I believe if it is not already included. a DVI to HDMI cable should work, sound you can funnel through line out / earphone out.
I think Monday next week Mr Jobs does a Keynote at the developer conference which means new product introduction. Since the MacBook and Macbook Pro Upgrades were released earlier they will for sure show something big. Could be a reworked Imac, could be a replacement for the 12" powerbookI am hoping they show an enhanced media server based on the Mac Mini format.
