How do I download the videos?
- To download, right click the file type you would like and pick “Save target as…” or “Save link as…”
Why should I download videos from Channel9?
- It's an easy way to save the videos you like locally.
- You can save the videos in order to watch them offline.
- If all you want is to hear the audio, you can download the MP3!
Which version should I choose?
- If you want to view the video on your PC, Xbox or Media Center, download the High Quality WMV file (this is the highest quality version we have available).
- If you'd like a lower bitrate version, to reduce the download time or cost, then choose the Medium Quality WMV file.
- If you have a Zune, WP7, iPhone, iPad, or iPod device, choose the low or medium MP4 file.
- If you just want to hear the audio of the video, choose the MP3 file.
Right click “Save as…”
- Mid Quality WMV (Lo-band, Mobile)
- WMV (WMV Video)
Are you a DirectX game developer? Well, you might check out PIX, which stands for Performance Investigator for DirectX. Mike Burrows demonstrates the tool and how you'd use it on Windows games to profile your game's performance.

Umm, there's absolutely no way that you could directly use pix to cheat in any game.
Plus, I believe there's something you can do to your program to prevent pix from grabbing information from it (can't remember what offhand). Though a quick test reveals that it does work with half life 2, profiled the main menu successfully. Though grabbing 293 frames of that simple scene took 165 mb.
That all said, pix is an amazing tool! I've used it several times to find performance problems in my own graphics engine and fixed them as a result.
Redirect output to null, redraw the scene on the display except minus the textures for the walls, giving you a nice shoot though walls cheap in CS. There is one example. How about glowing models via the same method? How about an aimbot via finding models using the graphics calls?
* Shoot through walls have nothing to do w/ null textures. Walls are data structures, not textures.
* See through walls are possible, though, Not sure how you would modify PIX to allow that.
* Aimbots exploit the network communication protocols, not graphic calls.
