No. In addition to the video version of the lecture we have also created "audio only" versions of the lectures. These lecture are in the mp3 format and can be played on any device that will play a mp3 file.

Yes you can on a computer, but not on most portable devices. The free Quicktime 7 player comes standard with a speed up / slow down function.

1) From iTunes, right click or ( cmd + left click on a Mac ) on the video.

2) From the pop-up menu, choose "Show File" on a PC or "Show in Finder" on a Mac. This will show you the actual media file on your computer.

Yes and no. You cannot affect the speed of a video on the iPod, but you may be able to on other devices. That will depend on your device's media player.

The audio on the other be can sped up or slowed down on the iPod. In order to do this you will first have to change the file type. To do so:

• Download the lecture you need from the "Audiobook/iPod Only" tab.

• Add it to your iPod as you would any other file.

• On your iPod the lecture will be stored in the "Audiobook" menu option in the music tab.

• Select and start playing the lecture.

• With the lecture playing, press the center button 4 times. You should get a screen that screen that says Speed and either Slow, Normal, or Fast.

• Use the click wheel to change the speed.
