OGG

I like the concept of OGG. It provides a free way to display media on the intertubes. Kinda like PNG replacing GIF when Compuserve decided they wanted $$ for something people had been using freely for years. Similarly, the guy who came up with MP3 decided he wanted royalties years after the file format had become popular (years after it had been created & shelved), so OGG is the way to go if you aren't rolling in the bucks & don't want to use YouTube & their horrible compression.

Ogg is a free, open container format maintained by the Xiph.Org Foundation. The creators of the Ogg format state that it is unrestricted by software patents and is designed to provide for efficient streaming and manipulation of high quality digital multimedia.

While most browsers support OGG, Apple & Microsoft do not. There are plug ins for their browsers, however.
Well, there were. With Apple's 'upgrades' the OGG plug ins are now broken.
It wouldn't cost a thing for these behemoths to support the formats, Theora & Vorbis. I have read that Apple & Microsoft might fear patent challenges, but, apparently Google & Opera don't have those fears.
But Mozilla, Opera & Google don't have their own media file formats. I am sure that implementing support for these file formats would shutter both companies in a week.
Seriously, boys, just plug in the code & let it be. Your stuff is better but sometimes people just want to post videos of lamb chops in space.
