Ok, I'll go the extra mile here...
Windows Media 8 makes your files look fantastic. It's not like previous versions. You have to use the
Windows Media Encoding UTILITY to encode the files.
Real 9 is a little bit better looking. Real is an overall pain in the ass for the surfer when they have to upgrade because, as you probably know, Real tries to sneak all kinds of extra options and bullcrap in with the necassary upgrade. But it does look a little better. You can use
Cleaner to encode both Real 9 & Windows media 8 as well as every other format (avi, mpeg 1,2,3 & 4, quicktime). I use the Windows Media Encoding Utility only because it gives me more options.
You can use all of these formats for your AVS sites. Get familiar with Cleaner so you can take advantage of the extra benifits like meta tags which allow you to trigger other pages or frames to open up in your sites.
