Best hint I can give you with things that don't like to play well is to start the video, then pause it, the vid will continue to stream and cashe so that if either your connection or the hamster servers are a bit on the slow side you can let almost the whole thing load and then start play again and the vid will work as if it is playing from your local drive.
