I have been trying to use some of the sopcast football streams however a lot of them try to load (message 'connecting to channel.... appears) but do not reach the 'buffering' stage. Instead it spends a few minutes with the above message and ends with 'can not retrieve data'. The used to happen very occasionally but now most of the english channels do this when I try to open them; is this because I need to change a setting or download something?

Help!!!
