I just installed it on my Pearl (T-Mobile), fired it up and chose the first video clip at the top -- it took a few seconds (15?) before the download actually started for real, and downloaded from that point very slowly (a lot slower that a 37sec clip should take, imho). But, it played -- not the best quality by far, they can do a lot better to be BB optimized...not to mention the clip is a a meg in size.
