DVD-R Dual layer for Ps2 backups. Any Success?

[maxxxpain]

I noticed that DVD-R dual layer discs have appeared , it seems that at the moment verbatim are the only company making them. Has anyone tried using them to make a back up of a dual layer playstation 2 game original?

I was thinking this may have a better chance of working on older playstations that may have had trouble with DVD+R discs.

I have the first messiah chip in my machine and its a few years old , i might try one of these DVD-R dual layer discs to see if it works , would i be right in saying that you need to patch the ISO with the toxic patcher in the same way as a dual layer DVD+R disc?

To this point i havent tried making a back up with dual layer media because i thought my machine may not read the DVD+R discs properly . I know my machine could not boot the original copy of the game God of War , so i could be in trouble wether i use DVD+R dual layer or even the new dual layer DVD-R version.
