I noticed the downloads aren't available yet too, but the Press release is only approx 1/2 hour old. The beta downloads will probably be there soon IMO.
I am a little confused on the restrictions on the beta download. It says.
"You can create projects using all supported media types (excluding AC-3, MPEG and MP3)"
I know you can not open these files until the final release due to licensing, but can I create mpeg files and 5.1 surround sound files and burn a dvd with the beta or not ?
