I did e-mail ISS but they gave me a link to these forums...helpful haha.
I don't think it's 4OD in general as my boyfriend lives off campus and it works fine on his computer. I do use firefox and I've tried looking at the settings and trying a different browser etc. to see if was just my computer but I assumed all the settings were right as bbciplayer still works fine(and while we're on the topic, channel 5 on demand doesn't work either because it thinks I'm not in the UK. I only wanted to watch the Ross Noble program, grr)
