I seriously doubt that you could put all the instructions on a single DVD - YES there is that much to learn if you wish to learn ever single detail about every aspect of the keyboard.

In order to be effective, and to make it so that those that wished to watch the instructions, the Tutorial would have to be segmented and indexed to each function separately, something like the user manual, which, of course, most people fail to ever take out of the plastic bag. Fortunately, for those individuals, there is the PSR-Tutorial site which has a massive lessons section, which in some instances include photos and videos. Ironically, many folks that frequent that site rarely go to the lessons section to find answers to their questions. Same goes for the styles section, which holds 10s or thousands of style files, all free to download. Before they ever think about looking at that section of the forum, they post a question asking for a style file for a song.

I give up!
