It happend couble times that internet radio that is at N800 desktop stop working.. There was just window/test that it was buffering, but nothing happend, no bar.. Only thing that did help was close buffering window and press 'play button' of radio again.. Sometmes iy didnt resond first, but later it did work again and start buffering and play ok.

usually means a dropped net connection. reconnect to wireless, stop the internet radio and restart.

the network stack on the 770/n800 seems to be flaky sometimes. i found that if i switched between apps that used the internet/my home network, sometimes the connection dropped.

Browser did work ok at same time, course I used it to try if net connection works.

Radio just said 'Buffering..' and bar didnt go anywere..

Then I did click cancel to close buffering window.. Play button didnt start buffering/didnt do anything.. and later play button did respond again and buffering -> play. This happend couple times yeasterday. (First day with N800).

Maybe it's related and maybe not:
I noticed that sometimes the internet-radio applet doesn't show a bookmarked station and doesn't work. When this happens, mediaplayer also refuses to play anything, or even load. Sometimes this behavior disappears after turning my n800 off and on again, sometimes not. I think this problem is caused by mediaplayer being buggy.
