My MP3 player does not have fast forward or rewind buttons, so I have found a method for splitting up GeekSpeaks into manageable chunks:

1. Run mp3DirectCut – it is a 134KB ZIP file, and no install is required.
2. Open the MP3.
3. Click Special/Autocue.
4. Set a time value for the length of the excerpts. I like three minutes.
5. Click OK.
6. Click File/Save Split.
7. Select a folder to save to.
8. Select a base filename for the new MP3s.
9. Click OK.

You should now have several MP3s that will sort neatly in your player.
