I can give it a shot...
the short version -
-R/-RW/RAM are the only LEGITIMATELY recognized formats by the DVD Forum (
www.dvdforum.org ), this is the groups that OVERSEES and LICENSES the DVD format and DVD Logos... taken from the front page of their site...

Please note that the "+RW" format, also known as DVD+RW was neither developed nor approved by the DVD Forum. The approved recordable formats are DVD-R, DVD-RW and DVD-RAM. |
+R/+RW are, in reality, a 'rogue' format that deviated from the DVD standard. It's like making a audio cassette that had the two stereo tracks in a different position... looks like a cassette, fits a casette deck, but is different 'inside'.
That's not to say the -R format hasn't had it's share of 'rogues'.. in reality there is no such thing as 2x -R burning. The -R standards only had 1x and 4x defined originally (if my memory serves me correctly [ahhh! Iron Chef flashback]) and the Pioneer 2x was a kludge to compete with the 2.4x +R speed (and gave the original A03 drive a (roughly) equal paltform. that caused problems till an official 2x standard was defined.. by that time the 4x drives/media got common....
Most (if not all) of the original pushers of +R/+RW have now started making 'universal' burners (-/+ R, -/+RW) drives and a couple (Iomega, LG [or was that LiteOn?]) have announced -/+R, -/+RW, DVD-RAM drives. I suspect this was in response to the higher compatibality ratings of -R discs and the falling market share (to be fair, most of the -R vendors have added +R/RW capabilites in their drives also.. however I would venture it was to CAPTURE a larger market share than just to be compatible..)
Probably the two best combo, PC drives now are the Sony DRU510 and the Pioneer A06.
This 'merging' has not appeared in the standalone market to any real degree.. there has been some discussion on the Sony standalone and it's support (or lack thereof) of +R.
Yes, -R/-RW is the more compatible of the formats out there as tested and reported by many many magazines/webzines.
-R/-RW media is less expensive across the board also.
+R has an 8X PC burner out (Plextor combo.. 8x +R / 4x -R) but no sign of any quantity of 8X media.
DVD-RAM has been around a while, and with the exception of people who want to diss the format, will be around a while longer. All of the current crop of Panasonic DVD set-top players will play DVD-RAM discs. Thompson in Europe has annouced DVD-Ram capabilites in there new players and you will probably see more makers add the compatibility soon.
DVD-Ram is the ideal 'editing' format since when you remove a segment (commercial) it's GONE and the space is physically removed from the program and the space reclaimed.
As one person pointed out.. DVD-RAM can do a trick that +R/+RW can't do... be recording on one part of the disc and playing back another.
