I was thinking of just making a data DVD-R so that you could access this stuff from your computer's DVD-ROM drive.
Those video files are not high enough quality to bother putting on a DVD for viewing in a standalone player. Also, you couldn't do much with the audio and document files that way either.
I just mentioned a DVD-R because those video files over at
www.kel.cc/downloads/TaxStuff are just too large for a single CDR.
