I have installed wiikey with solderless clamp over chip and I can not get any dvd's to work and can not upgrade or setup my wiikey. Also my wii is version d2b with 2.00u firmware. Could the 2.00u firmware be the problem?
What program are you burning the isos with? Also did you install the modchip yourself or did someone do it for you? Has it ever worked on other backups that you didnt burn yourself? Did you test to make sure it was installed right?
