If you ask Apple to give us a new version of Front Row - forget it:
1.) They want to sell Apple TV.
2.) Font Row was based on QuickTime (32 bit). And now they prefer "AV Foundation" which must convert most of the movie formats before playing it.
If you say that Plex and XBMC is not Mac-like as Front Row used to be: I would like to agree. I tried to explain my family that DVDs are displayed as folder... and that they have to open the subfolders (VIDEO_TS)
and select one file... They just said: trash it!
If you are searching for a media center which can access your picture / movie folder and start iTunes DRM (protected) movies: try nessMediaCenter.
But please do not expect that this media is displayed within this application. These kind of media can only be played by Apple products - so what nessMediaCenter is doing is to launch iTunes and start the movie. Sometimes it works, sometimes iTunes starts the movie and ... well, I would call it "fails"? But you can then control iTunes with the Apple remote control... I do not now any other (better) solution. Not a beef, but...
I know that many people like Plex and XBMX, but I would like to mention other disadvantage:
1.) There is a background thread which is observing the folders (local "computer speed") and trying to get metadata ("internet speed" if you are browsing at the same time).
2.) Plex might rename you movies if the metadata is wrong. I was surprised about the movies I saw ... until I recognized that it was just caused by wrong metadata.
And last but not least: all you file names will be cataloged over the internet, because Plex is sending these informations to its own server. Which means: if you have videos and you would not like to tell someone else, then using Plex might be a bad idea.

Finally I would like to say that there are several solution. Which one you choose is up to you.
