DVD-R Authoring are generally used for movies and other types of visual media. General purpose is for data storage, backups etc. Theyre not THAT different because with most DVD-R drives you can use either for different purposes.

A DVD-RAM drive takes those bulky DVD cartridges. They are brittle and are not playable in a traditional DVD player. They can only be read by a DVD-RAM drive.

The complete answer, from Pioneer's viewpoint is available at this URL:

http://www.pioneerelectronics.com/Pioneer/Files/DVDR_whitepaper.pdf

What they give at that site is the history of the two types of DVD-R media, as well as an explanation of why.  The two types of media are written by two different types of lasers; therefore, with a given DVD-R recorder, you don't have a choice:  you can use whatever type it was designed for -- General (650nm wavelength) or Authoring (635nm wavelength) (that is not to say that you couldn't have both types in one recorder, but it would be an even more expensive drive - many thousands of dollars).  Generally speaking, if you have a consumer DVD-R (that is, you paid less than several thousand dollars for it), then you can only use "General" media.  Your Apple G-4 probably came with a Pioneer DVR-A03.  If that's your drive, then you must use "General" media.

The "Authoring" media are for professional applications and has been used for several years (copying CT scans for medical applications, for example).  The "General" media are designed for the consumer market and contain content protection measures that make it physically impossible to make bit-for-bit copies of CSS encrypted entertainment titles.

I hope this helps to clear it up.  Bottom line is, don't buy the wrong type of media for your drive.  You probably need "General."
