I've had a similar problem where the disc continues spinning in the "loading" mode and then finally goes to "disc error." So, I opened the cover of the player, and noticed that the disc was not spinning as fast as I expected, and there was an extra unpleasant sound when the disc was spinning. Thus, I suspected there was an issue in the drive motor system: either the motor drive board, the motor itself, or the contact to the disc. I saw that there was dust accumulated on the rubber contacts to the disc, so I cleaned them with a q-tip. I then resetted the system, and the disc was the spinning normally again, and everything worked like before! (Other things I have tried in the past were cleaning the lens and updating the firmware, none of which worked) I hope this helps!
