I think that this interview with ATI Stream team
resolves all ....

Unfortunately ATI Stream optimization in PowerDirector DOES NOT live to the great expectations ATI and Cyberlink have been creating for so much time!
First of all, the ATI Stream support update is NOT here yet. It will be made available early February.
But the main and critical reason for one to be disillusioned is that although ATI stream will be used for MPEG2 and H.264 video transcoding, it will be used to create videos using ONLY the iPod profile and none else !!!!
That is ATI stream capabilities will be used to produce ONLY 320x240 videos at best, while the NVIDIA CUDA counterpart will be used for AVCHD, M2T and various portable video profiles !!!!
I am very sad with this development and can only wish that ATI stream support will soon be extended to additional profiles or else I will have to turn to NVIDIA for serious video transcoding and processing very soon.
Should we have waited for so much time since last June and pay just to get what already ATI Converter provides in the GPU arena and free ???
Can ANYBODY tell me the reasoning behind this, unless some more profiles are on the way be supported REALLY SOON ??

Look at the announcement link below - PowerDirector section:
http://www.cyberlink.com/stat/events/enu/2008/q4/ces2009/index.html
It seems that the update will come out probably after CES 2009.
As far as I have tested so far a Sapphire RADEON 4850 1 GB in my Home Vista Premium, with the exception of mobile low bitrates, everything else works very fast; with the slowest time being 4 mins for more than an hour DVD movie

Hello to everyone in the forum !
I have been dealing with the GPU assisted transcoding issue since last June very thoroughly !
There are some things that need clarification and I will try to do it for you !
PowerDirector's current GPU assistance provided by NVIDIA CUDA DOES NOT involve transcoding AT ALL !!
It is all in the filtering/rendering area and currently the ONLY tool to provide NVIDIA GPU assisted transcoding is Badaboomit !
On the other hand, ATI is going to provide GPU assisted transcoding using ATI Stream technology as officialy presented on November 13th. See more at: http://ati.amd.com/technology/streamcomputing/index.html
Furthermore, RADEON 4800 series has BUILT IN HARDWARE TRANSCODING for H.264 and MPEG-2 formats. You can see details at:
http://ati.amd.com/products/firepro/Siggraph_2008_video_encode_final.pdf
It is obvious from all above that ATI's transcoding solution is supported BOTH in software and hardware level. That means that using a 4800 RADEON series card one can achieve VERY FAST transcoding speed regardless of the CPU installed.
The crucial issue is that noone needs to upgrade the whole system; JUST the graphics card will be enough !!
