From what I have read the Verbatim DataLifePlus media is the most highly
praised.  I have personally used TDK (DVD-R 2X), Verbatim DLP(DVD-R 8X),
Sony (DVD-R 8X) and some no-name house brand (well it says Teon on the
label DVD-R 4X) and all were fine for data.  Trying to copy a video DVD (a
personal DVD-R not a copy protected or encrypted commercial one), I found
that some DVD players (a Sansui DVD-RW recorder and a Samsung DVD player)
just refused to read it no matter what brand of media I used.  But my
other two players (a Phillips portable and a CyberHome AC/DC player for
the car) had no problems with the same copies of the DVD-R on any of the
media. These were written using mkisofs2 and DVDAO under eCS 1.2 on my
T42p with an IBM multi-drive.   So I think it depends on what you want to
do, and probably more on the DVD writer than the media.  If you want the
longest life out of a DVD, then it seems everyone recommends Verbatim
DataLifePlus.

No idea on compatibility with the next generation of optical storage.

Hi All,

And for the definitive answer -- see http://www.acpi.info/

It allows amongst other things for OS/2-eCS to power-*off* ATX boxes 
which nowadays don't have access any longer to APM 1.2 capability in the 
BIOS.

I have used a variety of makes - all of which I can write and read. The 
issue can be with the "other end" some older DVD disk drives seem to 
have problems with reading some makes. If you are talking about a 
Video-DVD rather than a data one, it is often the case that some makes 
work and some don't.

Of course since 8.5GB Dual-layer DVD burners are now sub A$100 if you 
need to use dual-layer you'll need the more expensive disks but again, 
beware of  where it is going to be read. A single layer data DVD-Rom 
drive will not read a dual-layer disk.

Of the makes of burners, they're all pretty equal. Pioneer is one of the 
"safe" makes from an OS/2 point of view and from a compatability 
viewpoint as they have always been one of the first to release the new 
DVD features.

If you are uncertain, on which make of disk to use with your particular 
drives, buy individual disks if possible and then go back and buy a 25 
or 50 pack once you have a make you're comfortable with.

Cheers/2

Ed.
