everytime i'm trying to run iso's i get error (80020321).
it shows the game icon but it won't run it.
i have tried three different games (mortal kombat unchained, midnight club la remix, and tekken dark resurrection)
i also have some homebrew games that run fine as well as my emulators.

i am running cfw 5.00 m33-4

any suggestions on what the problem could be?
