Can these burn faster?

Hi, I’ve been reading this forum without reason to post for the last couple weeks but now I have a question. My dad gave me a spindle of dvd-r’s that he bought accidentally (thought they were cdr’s, doesnt really know the difference) that nero is identifying as RITEKG03. These are limited to 2x on my nec 3520 and I was wondering if these are capable of going faster. I checked out liggy’s firmware but this media isnt listed among those that he sped up. Thanks.

They may go to 4X, i’ll try them in the next beta.

Thanks alot.
