Really? How are DVD-RAM more reliable than DVD-RW/+RW? Is there some additional
error checking in the disc format? I'm assuming it's not a media or
"manufacturing" issue you base this on.

You can be more direct that that: DVD+RW customers were lied to, and this was
the basis of a class-action lawsuit against HP (or did they settle before class
action status?)

I'd say DVD+RW playback support is even lower. I based my recorder purchase on
this very issue (almost nothing else). Hanging out in the "DVD Recording"
forums of Digital Digest, VCD Info, etc. I concluded there were many "DVD+R
experts" who didn't even have a burner yet, and were just buying into the
information at dvdplusrw.org.
You can get a fair idea of compatability by looking up your player at:
http://www.vcdhelp.com/dvdplayers
Unfortunately there is no summary of -R/+R compatability % in this database.
Note that if there are a low number of reports for a DVD Player model, the data
is inconclusive: "failures" could simply be with one brand of media, as was the
case with my older Pioneer drive. So an "unsupported" model may still work (if
you are lucky).
