can anybody give me a hint why my new Motorola Milestone does not play mp4 properly - only sound is ok, but no video. The same file is being played on iphone ok.
Have a look at the files in here

Many of them are 854x480 or 848x480, 30fps, 1500kbps video, 160kbps audio H264, and play fine on the Droid/Milestone.
The iPhone, unlike the specs mention, can actually play 720x480 as a max resolution.
