Hi, I am very new to the wii modding scene. I have not yet recieved my chip yet (i just got the wii 3 days ago) but i do plan on ordering the d2pro9 v2 asap. I would like to share some of my results though. Now i can not vouch for any dirty disc errors because i can not test them yet however i can show you the DVDInfoPro graph of what i got.
Media: Tayo Yuden CD-R about a year old since i have a stack of like 99 from a year ago.
Drive: PBDS DVD+-RW DH-16W1S (Im on my brothers vista pc idk anything about it. Its a cheap $400 dell. i think this is it w/e it means)
ISO: SUPER MARIO GALAXY
Burn Speed 4x
This isnt photo shopped... idk if many people have been able to achieve such high rating... but like i said, just a normal pc with some nice media, seems to pass quality check. However DRE still remains untested, once i get the chip installed i will let you know
