I do a lot of exports for PowerPoint. Here are the WME settings that I use, and have worked reliably on the laptops we use for presentations:
Audio: 192kbps, 48kHz, stereo CBR
Video size: 640×480
Frame rate: 29.97 fps
Video bit rate: 2000K bps
Video smoothness: 0
Decoder complexity: Auto
Under the processing tab:
Deinterlance
This makes my presenter very happy. He’s a former network TV guy, and a stickler on quality.
Make sure you put the .wmv file on the presentation computer harddrive, and turn off every other process except powerpoint. You may get full screen video to play properly 9 times out of 10 pulling it off the CD/DVD drive, but the 10th time will always be your most important presentation .
