Instruct: Classify Amazon reviews into positive or negative sentiment
Query: DO NOT USE UNBOX!

In response to the guy who said not to post technical complaints in the movie review section I say: show me where I can make my complaint with this garbage player as easily and as visibly as I can here.Normally I love Amazon. As a matter of fact, I did most of my Christmas shopping here. As an online store, they are tough to beat.This player, however has just taken the top spot on my "worst video players ever" list. It has frequently locked up my computer so badly that I couldn't even bring up the task manager to close the application.Even when I was able to view my movies it would take about 30 seconds for it to register that I wanted to pause playback.In short:Worst Media Player EVER!
