If you are looking for some results please take a look at the mails from Andrew Stevens in the thread: Re: any mpeg2 encoder faster than mpeg2enc? http://sourceforge.net/mailarchive/forum.php?forum_id=2356&max_rows=25&style=flat&viewmonth=200212&viewday=28
And that mail is also interresting: http://sourceforge.net/mailarchive/message.php?msg_id=1372215 And te reply from Andrew. > The cause of this is that AMD had a considerably faster implementation > of several MMX primitives than the Intel implementation.

At least at home my Athlon 1.4GHz (No Rating), is encoding as fast as the 1.9GHz PIV at home. Together they are fast :) auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard ------------------------------------------------------- This SF.Net email is sponsored by: INetU Attention Web Developers & Consultants: Become An INetU Hosting Partner.
