Not sure about 'any', but i have always been able to play them without problems, which I cannot say for .mov, .avi, .wmv, .swf and others. The main difference is that mpeg videos are downloaded, and then played (this sometimes happens in the browser if you have a plugin installed) while other formats will stream (they start playing when part of the file has been buffered), but are not so portable, across platforms or browsers. http://www.w3schools.com/media/media_videoformats.asp If you can, I would use whatever format you prefer, and then offer mpeg as an additional option for users to download if your solution doesn't work for them.
