My son sends me videos he takes of my grandson on his iphone and when I try to play them on my Samsung Epic 4G the quality is terrible, very fuzzy, some are barely watchable. Is there a conversion I should do first? Or use a different video player? I'm using the stock video player but I've also tried MX player and Quickpic. It gets a little better but not as good as it could be. Any one else have ideas?
