I have Kaleidescape in my theater (Strato and Terra server) and the interface, ease of use and feature set is awesome. Even my wife and scroll through the movies and play one
Is it worth the money? Probably not.
Some cool features of K are (besides the cool user interface):
1. Preset demo chapters that allow you to directly access certain scenes on any given movie you select to play. For example, select 'Ready Player One and with the 'Play Movie' option is 5-6 demo scenes for quick, direct access.
2. They preprogram in movie aspect ratio so screen masking automatically moves to fit picture.
3. No trailers or FBI warnings at all - go right to the movie if you like.
5. You can cut and paste your own demo clips from any movie you have into a demo file.
6. Can select movie by genre, director, film type (comedy, thriller, etc)
7. Download times are 15 minutes to an hour depending on speed of internet
8. Interface is easy to use and nice looking.
