DVD-RW Incompatibilities? 254
rekkanoryo writes "It seems that there is some trouble brewing in the DVD-RW camps. According to CNET, new, faster 4x DVD-RW media may not be compatible with older DVD-RW drives. The DVD+RW camp is confident this won't be a problem for them, but the -RW backers think it will sometime in the future when even faster media starts to appear. Also mentioned is a dual-layer DVD+R capable of holding up to 8.5 GB of data per disc and the problem with really old DVD+RW drives not being upgradable to support write-once DVD+R media."

A DVD+ and DVD- disc will read in virtually any drive, period. Unlike a Beta tape, which will never read in a VHS VCR.
More importantly, at the time of the format wars, a VCR cost $400, which, translated to today's dollars, probably feels like buying an $800 item right now. Also, the VCR was expected to last a decade back then (as a matter of fact, I still have a 1984 Zenith VCR - working). DVD burner for your computer is expected to last 2, maybe 3 years prior to replacement and costs $150.
The absolute worst you can be screwed is:
- Lack of media being produced in your format (You lose $150 on the drive)
- Having media left over when your drive dies that will not work in burners now being sold (You lose... hmmm... in my case $50)
The worst you could be screwed during VHS vs. Beta format wars was:
- Entire tape collection obsoleted (if you bought pre-recorded tapes at the time, minimum $100, likely many thousands of dollars if you were an enthusiast)
- Tape collection cannot be recovered into other format (assuming all Beta/VHS VCRs dropped off the face of the planet) (priceless, if you managed to tape something that will never be broadcast again, or if you had a Beta/VHS handycam)
- Lack of media being produced in your format ($400 then, $800 now for a new drive)
- Having media left over when your drive dies that will not work in burners now being sold ($50, maybe...)
We're talking a lot of difference in losses here. $200 is manageable. Thousands of dollars, and a loss of priceless work isn't.
