When trying to watch stuff on wifi on my iPhone from YouTube or iplayer, more often than not it freezes at some point during the session then refuses to restart. It's very annoying - doesn't happen on 3G but I can't use iplayer on 3G as I'm on O2 and they don't support it. I don't think it's our router - ds doesn't have problems on his Nokia. But maybe a comparability problem? Need to fix it - I can't keep ds quite with videos of space shuttle take offs if I can't get YouTube working!
