I have a website that is used primarily in schools. A while ago, I had tried downloading some youtube videos (and converting them to wmv and mp3 or mp4 files I think) and had put them on my site. This way, they wouldn't be blocked in schools because they wouldn't be coming from youtube. The problem was when I tried to watch them on my website from my school, the videos played but took forever to load because the file sizes were too big. I want to try converting youtube videos again. I recently heard about progressive download. Is flash the best way to go with this? Do I want to embed the flash file with an FLV video file and an SWF file to play the video?
