For those of you who do not
want to listen to the information at the beginning of each class given to my
students and who only want to listen to the recorded lecture, I post a lecture
starting point in minutes and seconds on every (w) version of the notes. The
MP4 Player allows you to fast forward to this starting point. The material at
the start of each class recording gives excellent scheduling, test review, and
lab report construction information.
To fast forward the MP4 download, pause the recording, allow the recording to
load past the start point, then resume the playback from that point. It may
take three to four minutes (or longer) depending on the speed of your internet
connection for the recording to download to the starting point.
