Did you know that you can record television video on regular CD disks? Do you know the difference between DVD-RW and DVD+RW? If you are interested in creating CD-ROM and DVD disks but are confused by all the buzzwords involved, I can point you to two great resources:
Andy McFadden's CD-Recordable FAQ is available at: http://www.cdrfaq.org
Jim Taylor's DVD Frequently Asked Questions (and Answers) can be found at: http://dvddemystified.com/dvdfaq.html
These are long and detailed documents; you won't read them all in one sitting. However, they explain things in plain English, not in techno-babble.
