Yes - I had actually stumbled across Plex since posting my original question and have been playing with it on my iMac. It is very nice indeed and a whole load more functional than Front Row yet with a very nice user interface. The information and graphics it automatically downloads on movies in your library is especially impressive. Apple would do well to consider taking over this project and incorporating it into the next release of Front Row and Apple TV! Incidentally, I see that it is a port of the popular XBMC application, that started life as the open source home theatre application for the X-Box, but has since gone on to be the main home theatre applications for Linux. Indeed, Plex has swung it for me - it is a class above what the Apple TV can provide and justifies the extra expense of the Mac Mini. In terms of user interface, it is no more difficult to use than Front Row, but because of the power of system it is more complex to set up (but not by any means impossible). Integration with the iLife apps is automatic.
