Some videos wont play on ipad 4

[lfcsmithy]

Hi there....i stream the F1 2012 game. I can watch all my recorded stuff on my pc with no problem, but only certain ones play on my ipad 4. Is it something to do with the quality settings within procaster?? I recorded some tv shows and they play fine on ipad, but my races wont play.

Any ideas guys??

Thanks
