What are the differences between the various video players available for Android? Which one do you believe is best?
There are so many out there so it's very hard to say.
Personally I've only used RockPlayer. It's very good. Plays all modern media files, functions very smoothly without any hiccups.
Another popular one that's been getting some traction is VPlayer. I don't see much different between the two... VPlayer is new to the game so the features are still coming.
Personally give them a go and see what you like best.
