I was wondering if there was any HD media players that could pull information about the file like description, actors, and more. I've used MediaBrowser on Windows Media Center and that works perfectly. I was just wondering if any of the current media players are capable of something like that since I dont want to buy an HTPC.

The video jukeboxes available on NMT's can.

For example YAMJ, UMC (Ultimate Media Collector), MLMJ etc.

The EVA 9150 has a piece of software that you can use to tag the movies. Once that is done it displays movie info when you scroll through your movies.
