Going on the BBC iplayer website on the n900 and attempting to play a video inside MicroB results in a video and audio experience that's jerky, slow and generally unwatchable. If you download an iplayer video however and play it in media player, it plays perfectly.

1) Why is this?

Playing HD content on the n900 is a joke, it just won't work, yet viewing the 9 trailer (Which looks HD to me) in media player results in perfect playback.

2) Why is this?

3) Will it ever be possible to play HD content on the n900 from sources like YouTube (Whether through a web browser or media player) and have fast, smooth playback?

Thanks
