Help burning using Recordnow...

[killa5]

Hey guys. I've already searched around for it and couldn't find anything on it. I made a DVD iso backup using DVD decrypter for my nba street 2 game. It's starting to chip in one area so I'm trying to make a good backup of it. The problem is that burning an ISO in Alcohol burns the DVD-R at 4x...and I want it to burn at 2x or 1x. Recordnow gives you this option but what settings show I burn the ISO under in Recordnow Max 4.5? What I mean by settings is...I'm pretty sure is should be DAO closed, but what mode do I burn it under? There are three...Mode 1, Mode 2 XA (Blocking 2336) - DDCD, and Mode 2 XA (blocking 2352)? Any help would be appreciated. I know that I could also make it to a .gi image but for some reason it sometimes messed up so I used DVD decrypter cause someone recommended it. Also, should check for Post-gap be checked in the settings too? Thanks again.
