I wonder what can be the real use of this app.
Sure, you get to create and manage playlists with this app. (a feature absent from QT Player, most certainly), but there are free apps. out there designed to add playlist to QT, so...
On the other hand, it relies on QuickTime and therefore suffers from all of QT's shortcomings (no dvix play-back, no mpg-2 play-back unless you pay for a plug-in, etc.).
Most definitely, this app. is not worth $25 at all. Not even $5, if you ask me, for one can always get Videolan, for instance: it plays everything, included all QT and QT-base apps. don't play (shame on Apple, really!), has playlists and... it's free.
