Finished the 3rd disc of Lost Odyssey this morning and put in the 4th disc when asked. Put it in and waited...waited...and...BAM...read disc error. Decided it was just a mistake and restarted the system, no luck. Tried cleaning it, installing it on the hard drive, and yet, still no dice. Did this numerous times throughout the day before giving up.
Went online and looked it up on Google. Seems the problem lies in the packaging when Microsoft put the disc in a paper sleeve, which created residue on the disc. Thanks Microsoft.
I've heard some success stories of actually putting the game in boiling water. Tried it myself. Boiled some water, looked for a pair of tongs, and inserted the disc into the hot water. Held that position for a good 2-3 minutes before taking it out, letting it cool, and drying it off with a paper towel.
Put it into the 360 and holy crap, it worked. Installed onto the HDD just fine and the game ran very smooth.
Putting a good 25+ hours into a game to only be shut out by a disc error message is a really bad feeling...I'm just glad I didn't have to shell out some bucks to buy another copy.
So, yeah....that's really all I did today...what a life.
YAY for packaging.
