Can't get BBC iPlayer + other video sites to work - Linux Mint 10
I'm running Linux Mint 10 LXDE in the UK. I can't get BBC iPlayer, other TV sites such as ITV Player, YouTube TV videos or any radio to work at all.
Every time on iPlayer, it starts to load, and then I get an error message saying: content doesn't seem to be working right now, please try again later.
I have a very good Internet connection, latest Flash, a whole load of GStreamer codecs, MPlayer plugins for RealPlayer, WMP and Quicktime, Java and Shockwave. I have to go through a university proxy, but iPlayer works fine for everyone else here. I've tried with Firefox and Chrome, and I've emptied the cache several times.
Does anyone know what might be causing the problem? Thanks
