Panasonic's new "DVD Multi" drive now added equivalent functionality to a 1G
DVD-RW (2/1x DVD-R/RW, 12/8x CD-R/RW).  Drive pricing is around $300, which
makes it less than attractive versus 2G DVD-RW (

Okay, I guess call this a 4G DVD-RAM!  It's basically a 4.7GB (2/3G) DVD-RAM
with 2/1x (1G) DVD-RW, including CD-R/RW support:

         DVD-RAM:      2**
    DVD-ROM/R/RW:   6/ 2/ 1
     CD-ROM/R/RW:  32/12/ 8

[**NOTE:  I can't verify this, but it looks like these new, 4G DVD-RAM drives no
longer have reduced performance when "verify" is used?  If so, that's a _major_
boost in performance because DVD-RAM isn't really warranted (versus other
formats) without it. ]

So to update (and correct) my previous table (now two tables, "Current-G" and
"Current G minus 1"):

NOTES:
  *1*  3G DVD+RW drive had (?) small, nagging DVD-R issues (gone?)
  *2*  1-3G DVD-RAM  verify cuts performance by 40% (but not 4G?)
  *3*  Firmware update to DVD+RW 2xCLV/4xCAV now available (?)
  *4*  2G DVD-RAM drives do _not_ support DVD-R at all (only 3G+)
  *5*  1G DVD+RW drives do _not_ support DVD+R at all (only 2G+)
