Does the graphics card ALWAYS improve HD video playback?

[tokyotech]

I've been reading a lot of posts asking for suggestions on good GPUs for HD video playback. And people always respond with this or that card...

Now, I got a computer science degree from the University of Illinois specializing in graphics, and now I'm doubting my education. I was taught that you need to issue commands to the GPU through an API such as OpenGL, DirectX, CUDA, ect.. for it to offload any kind of processing from the CPU.

Everytime I watch an HD movie on VLC or WMP, the GPU temperature never increases, which is indicative that these players don't use the GPU. So my gripe is why are there a million threads on asking for a good GPU when in fact they should be asking for a good software player? Any GPU will suffice in video decoding; it's a dead simple process. You will not notice a difference between the 8800GT or the GTX 260 decoding video. What's really going to make the difference is the software that is using those cards.

Read harder homer, stop reading posts, start readin reviews and use you Comp Sci degree.

Which is why one of the questions asked of the posters here is "What do you want the card to do?" or "Do you game?" and if the answer is no, then the recommendations are usually directed toward the lower end cards.

The software you're looking for is Media Player Classic. Let me find a link.

Make sure you download the program through the links in this article. I tried just downloading the program and got the wrong one. There are 2 versions, and the one you want is linked in the article.
