   a couple of days ago, I dl and activated successfully this converter.
   according to my computer specs , I have a geForce 8400M GS nvidia graphic card.

   and accoring to the nvidia site that was linked at aiseesoft, this card should be supported by the cuda technology.

   however, when I go to the preferences of the total video converter, I cannot tick the box that says "enable nvidia GPU accelaration".

   what am I doing wrong?

   thanks for your help.

   You may need to update your video drivers first. Go back to NVidia's site and select the option to download drivers. You'll need to select the correct driver and OS before downloading.

   Hi ender,

   Just for the benefit of others that might read your post, CUDA is a (rather contrived) acronym that stands for Compute Unified Device Architecture. It is an architecture developed by NVIDIA for its more recent graphics cards (i.e. an engine) and applications written in certain programming languages such as Java and PERL can access this engine. This means that the can access the graphics card's processing power to speed up their particular application.

   Your card, the geForce 8400M GS, actually supports CUDA, so (bearing in mind that you have the latest driver installed) Total Video Converter should allow you to tick the "enable" box. I have two thoughts about why it might not allow you to do this:

   1. CUDA-enabled apps require at least 256 MB dedicated VRAM (i.e. not shared with system RAM)
   2. The "M" in 8400M GS denotes that you have a laptop, and I know from experience that the mobile versions of a particular GPU type don't always fully correspond with the desktop PC plug-in cards. It may just be a matter of incompatibility. Good luck with getting to the bottom of this.

   thank you ornitos for the lengthy response.

   I am afraid, you guess is correct, as I do have laptop, so it must be , that my nvidia cpu is unable to use this softwares cuda.
