Talking about Nokia 770 Battery life, when streaming Audio and video direct to the Nokia 770 is a very good point in general Karel.

When I have been testing the Nokia 770 with mplayer and or streaming music wirelessly through non standard and standard Nokia 770 Audio/Video players,I have noticed that the battery gets easily "severely caned" and does not last very long before going to the last bar and brown in colour. If I switch off the Nokia and allow it to recover for a little, while it generally goes back up-to approx half/way and green. (I like to call this the "Reservoir Impact" where the stream (Power) is being released quicker than reservoir can re-fill effect)

Now when streaming my AV to the Nokia 770 I do not want to care "at all" what the originating format of my files/URL's Feeds etc. being passed by the Server to the Player are on my PC, but I do care that the formats being streamed from my PC are easy on the Nokia's combined processing capabilities such that battery life is not quickly compromised.

This is where the TVersity (Transcoding) Media Server could be a real star, providing specific streamed formats that the Nokia 770 and other mobile devices of the future are able to support while maintaining an excellent battery life.

Here is another thread that discusses issues which I believe are related to a fast battery drain occurance. http://www.internettablettalk.com/fo...00&postcount=1
