Plays all files, best video scrubbing player

I like this app a lot. Tested a bunch of different formats (flv, avi, mkv, mp4) and it played them all. I don’t know why a previous reviewer said it doesn’t play audio. That’s not true. Audio came through without a problem.

Supports all the latest under the hood mac os x technologies.
Since its uses hardware acceleration, it scrubs videos the best of any player. I was able to scroll through a matroska video file without any lag. I was able to use the playback bar to instantly go to any point in the video. Matroska files usually choke any of the players I have used in the past and certainly don’t allow instant scrubbing.

Barebones in its feature set.
Does NOT have the ability to vary the playback speed. This would be my #1 feature request. I NEED to double speed a lot of videos I watch in school. Please implement this feature! If this is done I would have no problem recommending this player as the "go to" video player on the Mac.

No audio, no support

A waste of money. Apple shouldn’t sell apps that have no support.
