Advice with my app trailer

Hello,

Anyone else getting this? I can play HD Youtube but I'll be damned if I can watch a game App Trailers without it pausing all over the place. I certainly don't have great internet but it's enough for most streaming video.
Not so bad except that the player doesn't appear to do a lot of caching when you hit pause, so waiting for it to pre-load and then hitting play helps for about 5 seconds.

Anyone else getting this?
Any help will be appreciated.
Thank you.
