DVD+R are not compatible with all (older) DVD Roms?

My DVD Roms are to old for DVD+R Data Disks? :confused:
Or is this a general Problem of DVD+R Data Disks?

I have a LG GSA4040B two Weeks now, but i burn only 4 DVD’s until now.
DVD-R is ok, DVD+R Data Disks are not readable on all my DVD Roms, - maybe the Platinum Discs are not the best, or my DVD Roms are to old for DVD+R?

See my Results below:

As the DVD+R format is rather new in comparison to DVD-R/RW and DVD+RW,
most DVD-ROM drives don’t offically support the DVD+R format.

Some weeks ago I saw a retail box of a LG DVD-ROM drive with
the information “Compatible with all DVD formats EXCEPT DVD+R”.

When you read through the specification, most DVD-ROM drives
are (offically) only compatible with DVD-R/RW and DVD-RW,
the DVD+R format is missing on the compatibility list.

But, even the DVD+R format isn’t offically supported, DVD+Rs can
be read in “many” cases by these drives. But you can’t be sure.

I know my Toshiba SD-M1402 can read +R’s w/o a problem so far. I’ve burned 4 Memorex +Rs and they’ve all been perfect. Done only 1 -R, but that was perfect too. :slight_smile:

Which makes me wonder,with this and all the horror stories I get from people who have trouble with +R,why is it the manufacturers seem to be force feeding it
down everyone throat,money can’t be the only reason,it seems so counterproductive…:frowning:
