Re: arsclist CD-Rs can't be played on all CD and DVD players

["Richard L. Hess" <lists.rlhess@xxxxxxxxxxxxxx>]

Several comments about the compatibility issues from a small-scale, 
practical perspective:

(1) CD-Rs will not play on some DVD players because they only have one 
laser. The DVD requires a shorter wavelength light than the CD. This works 
well with CDs, but not with CD-Rs. As I understand it, many DVD players 
have dual lasers.

(2) My experience based on burning somewhere over 1000 CD-Rs is that I had 
problems with a very few CD players with Taiyo Yuden gold disks. When I 
switched to Mitsui Gold or Silver disks, these played in the known problem 
players and no new players showed "bad" -- and I've been selling them at 
concerts and such as well as using them for archival and demo purposes. 
This experience pertains to two copies of a Yamaha CRW4260 burner. Your 
mileage may vary. A suggestion, though, is to identify the "problem" 
players and then test a different combination in those players while also 
making sure there are no new "problem" players.

Good luck!
