I don't know if you're able to read this german article, but it may well answere your questions:
Generally it says, the best way to fast video encoding is the use of Graphic Cards (with CUDA or ATI stream technology) and an encoder using these technologies or to use special encoder hardware for this purpose.
Thanks for enlightening me!
After reading the report you've mentioned I've also found an interesting article comparing both ATI Stream and NVIDIA CUDA here.
Just one more question: So the built-in graphics adapter doesn't provide anything like that? Does it provide a GPGPU at all?
The embedded GPU of the board is a "Intel® Graphics Media Accelerator X4500HD". AFAIK Intel GPUs don't support any GPGPU operations. If you should think about buying a dedicated graphics card, keep the following in mind:
- AMD/ATI supports GPGPU only with cards of the type "HD48xx" (mentioned in the comments to the article you linked in your reply)
- NVIDIA CUDA is supported with the here listed cards:
Thanks again for your help. I appreciate it!
Actually I was striving for a powerful graphics adapter card without a fan. That's why I've bought the DG45ID. It was sold to me as silent yet powerful enough to handle Adobe Premiere Pro.
But now I recognize that Adobe Premiere Pro is not able to handle HD videos efficiently - despite their advertisement promisses. Since yesterday I've been told that Premiere Pro doesn't even support either ATI Stream nor NVIDIA CUDA or anything... :/

Thanks again for sharing your valuable knowledge with me.
I'm very keen to have a look at it!
However, I doubt it will help me find a remedy to my current problem. Even buying an appropriate graphics adapter wouldn't speed up Adobe Premiere's encoding in any way because according to Adobe Premiere Pro Hardware forum it doesn't make use of them
I've just seen the clip. Cool!
However, they seem to overcome the shortcomings in Adobe Premiere Pro by providing a special encoder to encode HD videos. Unfortunately this technique doesn't speed up editing. So it's still not possible to edit HD videos (i.e. AVCHD Lite videos) using Adobe Premiere Pro.
