Optiplex 1gb Xp
How do I access PureVideo, CUDA and PhysX?
So for Christmas I got an nVidia GeForce 210(1gb memory, 1238 MHz Shader clock, etc look it up on Newegg.) And I can't figure out how to use any of the above features to my disposal.
I have Windows XP Pro on my Optiplex GX620(3.2GHz Pentium 4 w/ HT, 2 gbs of memory, plenty of Hard Drive space), and I only have used the free DVD Decrypter, the free FairUse Wizard for anything to do with 'ripping' a CD on my computer, with low end resolution.
So do I have to buy a certain program(s) that gives me the option on whether I want to use PureVideo, CUDA, or PhysX? Or is there a path on my Computer settings that I can use to enable them? I tried enabling those options on the nVidia Control Panel, but they aren't there.
If you have an idea on how I can get my video quality to increase on my movies, that would be awesome. Thanks in advance.
CUDA, PhysX and PureVideo don't need to be turned on, but it would probably help to have the latest drivers from Nvidia:

1) CUDA: Nvidia Graphics cards have dozens (or hundreds) of processor cores, these can be used to do parallel processing, CUDA is a layer of software which allows programmers to more easily do this parallel processing on their data. To end-users this could mean encoding a video or helping in distributed computing projects.
Folding@home makes use of cuda: http://folding.stanford.edu/
2) PhysX: This is mainly a physics engine for simulating physics in games, to use this you would by a game that makes use of PhysX, the following games use PhysX:

3) Purevideo: I'm going to quote wikipedia:
PureVideo HD is a label which identifies NVIDIA graphics boards certified for HD DVD and Blu-ray Disc playback, to comply with the requirements for playing Blu-ray/HD DVDs on PC:
1. End-to-end encryption (HDCP) for digital-displays (DVI-D/HDMI)
2. Realtime decoding of H.264 high-profile L4.1, VC-1 Advanced Profile L3, and MPEG-2
3. Realtime dual-video stream decoding for HD DVD/Blu-ray Picture-in-Picture
The following software makes use of PureVideo:

Phew, hope that makes sense, I want 100 points for that 
starpc11 might be right, I thought PhysX would get installed with game or with drivers by default.
