hi
there is a way? i have tried the default mediaplayer but while streaming audio files from mediatomb without problems it does not seem able to even list the video files. i have tried mediabox and it lists videos and plays them, but you only hear the audio while image is fully black. it does not seem a codec issue as the files are played without problems if copied directly to the n900. any clue?

Is your MediaTomb configured to do automatic transcoding? Maybe this could cause the video format to be unrecognized by the N900.

no, it is not. Should mediabox play streamed videos?

in any case here goes my mediatomb config file.
