I want Video and I hope that any update to Media Streamer improves stability of video playback across the all claimed supported Nokia 770 formats when streaming on the network rather than playing locally on the device.

Also: Just to let everyone know that although Media Streamer does not currently playback Video and Pictures on the Nokia 770; I have been successfully using the Media Streamer as a controller to play Videos and Pictures on my TV using my SL300i. (via Twonky)

So in a nutshell, Media Streamer as a UPnP controller provides the majority of the Key Cidero Controller functionality on a small convenient tablet device. I can say that it appears to be very robust on my network, where even if the Wi-Fi connection drops on the network Media streamer seems to carry on elegantly without locking up the Nokia 770. I can therefore re-establish connection and carry on from where I left off in the Media renderer etc.
