It most surely would. If there's enough RAM for it. I've got a mjpeg
encoded 720p-video without sound here. It plays less than five minutes and
the file is 885MByte. When you add sound, even 16GByte of RAM (which is in
my opinion the maximum reasonably available today) can't hold 90 minutes
of video. So at least for full-feature films that's not an option.
