Hey everyone, thanks for taking the time to read this, i've got an unusual problem, that im not sure how to fix, so here i go...

I installed FreeMCBOOT and ESR onto my ps2 fat about a year ago. I was able to create ISO files from the games ive already had, for example, DBZ budokai 3, burn them to DVD and every game that i have done this for so far has worked perfectly. I use Verbatim DVD-R. I lost a few of my burned DVD games recently when i moved, but i still have the ISO file i created on my computer. I tried to burn DBZ budokai 3 again, on the same Verbatim DVD-R's in IMGBURN/DVDDECRYPTER/ALCOHOL120% at all types of burn speeds. The new games im burning arent being read by ESR. It tries to verify them, and then it says unknown disc in drive. All of my old burned games still work on ESR, but when i use the original ISO's to try games that i know are working, it doesnt load the new copy of the DVD.

Any insight on this would be awesome, thanks guys.
