High Quality youtube videos on the x10

[#1]

Okay, so when I use the youtube app on just about every other phone, there is sometimes a button at the corner of a video to let me upgrade to the high quality version of the vid. This does not happen when I use the app on the X10. Do I just need to do an upgrade, or is this some bizare thing that the x10 just doesn't do?

Whilst watching a video using the youtube application, press the menu button (left soft key) and select "more", a sub menu will appear in the middle of the screen - select the bottom option which will either be "watch in normal quality" or "watch in high quality" dependant on what quality is already being used.
