Super Smash Bros Brawl/Gecko OS ''No DVD''(?)

[VivaTheSaturn]

I'v been having this problem for awhile, and I just want to know why Gecko OS says there is ''No DVD'' ;_; I tried several times, took the disc out, wanted awhile,etc; but it keep saying there is no disc :/  I've tried other games, and they read perfect =O The Brawl Disc itself is pretty much good, nice and clean. I also tried rebooting with hooks, and it says there is no DVD ;_:

Any help? :(

Are you trying to load an back-up?
Because GeckoOS wont load backups.

can you load brawl normally (without gecko os) if not then you have dirty lens, if so then i dont know what the problem is

No, a regular original copy ;_; 

@ Jassim - Yes I can, but for some reason, GeckoOS keeps saying ''No DVD''
