I've been testing various videos and formats on my G1, but am running into odd refresh issues and errors some times, Does anybody know of any documentation for video specifications on the default G1 media video player? (does that thing have a name?) Many 3gp and mp4 videos play fine, but there seem to be some issues with file sizes and frame rates. It won't seem to stream if it 's over a certain size, and when downloaded to the sd card there seems to be another file size limitation where it will error and say "can not play video", but half the time it actually is still playing the video. Any specifications for video would be greatly appreciated! I wrote to HTC, but i'm not holding my breath for a response. Thanks!
