Version 2.0 DVD-R Discs??

[thomasbbb]

I was in CompUSA looking for some blank dvd-r discs and came across a 50 pack spindle of Memorex 4.7GB DVD-R discs... the packaging said they were "VERSION 2.0" DVD-R discs...

what is "VERSION 2.0" referring to? I've never seen that before.

"First there was the DVD-R Version 1.0 that provided a 3.95 Gb disc using a 635 nm drive. Later the 4.7 Gb disc was released as Version 1.9 using the 635 nm technology. Now DVD-R Version 2.0 media and drives are available. Version 2.0 media is 4.7 Gb Authoring DVD-R and can only be written on Version 2.0 drives. (1.9 and 1.0 media can be written in 2.0 drives as well)." - Taken from http://simplythebest.net/info/dvd.html

thanks so much... that clears it up.. saves me from returning the discs, since they wouldn"t have worked with my burner.

how does one go about finding out what version drive they have as far as disk version?

I purchased one type of dvd-r media that just wouldnt work at all! maybe it was a disk version thing.

just wondering.

i have toshiba SD-R5002 dvd burner if you know where to get the version type off it id appreciate it.

According to http://www.cwol.com/dvd-burners/toshiba-sd-r5002.htm , it seems that your drive is able to write to version 2.0 media. I would think that it should be backward compatible with version 1.0 media since it is version 2.0 compatible but the site doesn't mention version 1.0 compatiblity with the Toshiba SD-R5002.
