I attached a H264 video file to an email and after receiving it on the phone I clicked on the attachment. The video plays fine but there is no audio. This is the same thing that happens on a desktop PC using windows media player which doesn't support H.264. I'm curious now as to what video player is on the Samsung Focus and if it can really play H.264 video files. The big question of how to transfer a H.264 file from a desktop computer to the phone directly still remains my biggest challenge.I can alway convert my video files to WMV format and use ZUNE to do the transfer but I should not have to do that when the specs for the phone say it supports H.264 video.
