claesbas, I tried your videos on my N900. As others wrote, the built-in Media player only played DivX and XviD, while attempts to play other file formats resulted in a message about "unsupported file format". However, I also installed MPlayer (and KMPlayer as a GUI/frontend for it) and checked your videos with it. Mplayer played back *ALL* your videos except for MPEG-2 (which loaded but instantly crashed the player). The Flash video seemed to play just a little bit slower than other formats (it was not "frame dropping" but kind of very slight "slow motion") but all other formats played just fine, at the highest bitrate you made available. Hope this helps. Best regards, Michal Jerz My-Symbian.com My-Maemo.com (coming soon)
