I am enjoying the new Theater Views very much compared to what was available only a few months ago, but I must say that with a very large collection, when gliding through, my machine slows down quite a bit as the covers rotate or swing into view. I am not running a monster, but it should be plenty for a gui. I am suggesting that perhaps you do away with the 3D swinging effect of the covers and just have an apple style cover flow such that the entire collection of covers does not have to come into view when scrolling for a longer period of time. I hate to be another bringing up XBMC, as I do think most of J River is far superior, but most of the skins used in XBMC have a much better feel and smoothness to the presentation when a coverflow style is presented.
Just a suggestion.
Keep up the great work.
