Well, from AMD's site, only three apps are supported under Stream.

Cyberlink Media Show Expresso
ArcSoft?s TotalMedia Theatre
Power Director 7
Also listed is Cyberlinks Power Director 7, but I think this is primarily used for "capturing, editing and distributing HD video"
The problem is finding apps that support both CUDA and Stream. Seems ATI is limited to three apps (Power Director 7 can be configured for encoding) at the moment (unless they are not listed on AMD's page for some reason).
It looks like ArcSofts Total Media Theatre 3 has
CUDA support and
Stream support when upscaling. So this might be the only other app that can be used to compare CPU vs. NVGPU vs. AMDGPU.
From ArcSoft's site:
"When upscaling files in ArcSoft TotalMedia? Theatre, SimHD? utilizes NVIDIA® CUDA? and ATI Stream?, the GPU computing technologies, which not only offer large performance benefits but also balance GPU and CPU usage*, enabling running of complicated tasks which requires demanding calculations, without sacrificing output quality."
From your July 8th article link:
NVidia CUDA video application roundup
They tested 7 CUDA enabled apps. Three of which support Stream.
