Wiikey/Emulator DRE (disk read error)

Hey guys I've had the Wiikey for a while and it plays backups fine.
I managed to get my hands on two Emulator DVD's, SNES and Genesis.These games will play on my buddies Wiifree key. But they will not load on my Wiikey.Really strange and I cant figure it out.
By the way the media these dvds are on is TDK, I use Verbatim -R's for everything else and TDK's have worked before on my Wii.If anyone knows what I'm talking about and has suggestions or questions about my situation please let me know.

So... no worries guys I figured it out, lol. I guess no one could help me figure out the issue or knew what I was talking about.Anyway, all I had to do is boot a wiikey config disc and change the region settings to on, (save/apply) that's it.
I can now play SNES Sega NES N64 and others.I guess I will just help myself :D
