all my 720p videos are playing just fine.
i've tried several 1080p videos, but none of them plays and the app just return to the video information page after displaying the play controls for a few seconds.
there is nothing in the logs as if i never tried to stream these large 1080p files. the sample files, short clips cut from the large 1080p video files, play quite smoothly. the thumbnails of all my files are correctly generated.
i'm using air video server 2.4.6 beta3 on windows 7 32bit and the latest version of air video on iphone 4.
