[DM-MUG] Answers to the DVD Issue.

[Matthew W.]

I have not heard this and though I may be wrong, I doubt that the  
difference has anything to do with "higher quality" or lower. Each  
format writes sectors differently and it was a format war for no  
particular reason (please correct if anyone has a good source to share).

Older Macs had drives that used the slightly more compatible DVD-R,  
but that compatibility only means something if your DVD player is  
twitchy. The newer burners read and write both formats.

Even though they are less prevalent, I've found DVD-R's still to be  
slightly cheaper but the last time I bought was a few months ago.  
There's a lot of misinformation out there. One 2007 posting I looked  
up says that DVD-R doesn't have dual-layer capability. That's odd  
because I'm looking at a -R double-layer, 8.5 GB (maybe that's the  
difference-semantics) product on my desk right now from RiData that I  
bought at the beginning of the year.
