OpenCL and Xilisoft HD Video Converter 6


i hope i am in the right place here :?: and i hope that someone can explain this to me or point me in the right direction.

i have an ATI 4870x2 and have the latest, 11.4 drivers and Avio (not call that any more i know) installed.

When use DirectComputeBenchmark_v0_45b both Directcompute and OpenCL benchmark using the GPU.

When use a programs like Xilisoft HD Video Converter 6 or Cyberlink MediaEspresso 6.5, both are the latest versions and support GPU Transcending, to encode the GPU/s are not being used. Any idea why?
