Ouch.  I haven't done a lot of experimenting with media.  For the
most part, I've been buying the cheap stuff, as I am using it more
as "short term" storage more than anything else.  Except in the
case of game backups, so I tend to use "name brand" for those.
I don't worry too much about the storage issues, as I don't tote
them around outside the house, generally (just "disposable"
mp3 disks that I toss music/audio books onto for road trips).

I've also read their's is the best.

Iirc there was some indication that some media worked better in
some burners, too, so it really is a question of individual experi-
mentation.  Tough to build a matrix for this kind of stuff, and be

I do not have a first gen dual-layer Lite-On DVD burner.  Mine was
purchased around 6 months ago.  I have not yet tested it's dual
capabilities, but I have had no issues burning DVDs at this point.
I've backed up a couple of things I own for testing, after removing
the "extra" stuff to get it to fit on a single layer ("cheap" media). So
far, they've worked fine in the handful of DVD players I've tried.  I
haven't been able to test it for console backups--the consoles are
not here.

As an aside, making backups of this stuff is like learning an arcane
science...it's no wonder people go and get their consoles "modded"
with giganto hard drives so they can just load everything up and
ignore the individual pieces of media.  Once you have that, you
can just do HD->HD backups.  Wasn't there some company that
was selling a NAS with all the DVDs (and the DVDs already
ripped to the NAS)?

Yeah.  I haven't spent much time looking into this. I've been
avoiding spending excessive hours after work on my computers.
I did use this method to get a Sony CD-RW to work in my
graphite G4 tower a while back.  Replacing the firmware with
a slightly later model's made it recognized by OS X as
"supported", and the CD-RW worked fine.  I had to use a PC
to upgrade the firmware, though.

C'mon, you've been working in the computer industry long enough
to know how unlikely that is!  (Sadly.)
