tried to watch TV that I found at http://live-tv-channels.com/watch_tv_online.php?id=113 but even though downloaded the stream cannot open the channel - is there some software that needs to be loaded to permit this?

No Windows Media streams can be played on N800-N810 (I hope just at this time, I still keep my faith about that ability in the future)
Some users reported they were able to play some WM streams, grabbing the stream address, copy and paste in kmplayer...I don't remember very well, anyway never works for me.
Also keep in mind I am running OS2007; ignore if OS2008 could give some WM streams capability, but again I think no way so far....

That's mean you are unable to enjoy at least the 50% of radio/tv streamings available on the web...

You know, some might consider that a bonus...

Yes, in some sense....but can also be interpreted like a kind of censorship..

you could try using tversity and joost. joost have a lot of movies and feeds. using tversity i sometimes can get streams on the 770,but it is a bit hit and miss. just like a lot of things lately in the wonderfully buggy world of internet tableting!

Is Joost open now, thought it was only by invite.

I can stream most WM from sites using the default Media Player on OS2008. No copying and pasting needed.

...yeah im disappointed too..

i use on a daily basis TV TUGA, which is a site developed by portugal to stream many tv channels from all around the world, but the compatability with the internet tablet is extremely shaky.

well,i found the link on youtube. i downloaded onto pc and just confirmed my email reg. if you search for streaming on youtube,thers a guy who put up a 10 minute video on how to find all the streaming apps on the net, quite usefull.
