Radeon X1000 as a video co-processor

The german website Chip.de has tested a beta version of the software Avivo from ATI.
This application for PC allows users of a Radeon X1x00 to turn its GPU into a powerful video encoding coprocessor.
The supported video formats range from MPEG-2 to WMV9 and include of course H.264.
During a test with a Radeon X1300, the video encoding process was accelerated 5-folds! Of course the CPU, in this case an Athlon FX 57, was also fully loaded by the process.
This result will for sure be really attractive for customers.
Imagine, with iDVD, being able to burn a DVD while encoding it on-the-fly!
Of course for professional applications, such possibilities and features, will increase productivity, and saving times normally required for such encoding processes.
We are dreaming of testing such application (PC-only for the moment) on a PMG5 Quad equipped with a Radeon X1800 XT...
