Lost Season 3 Problems

[Verbal]

This is the second such thread I've had to start recently (the first being for another Disney release, Pirates 3).

I'm having a serious issue with all discs of the LOST Season 3 Blu-ray box set. None of them will play on my 60GB PS3.

Here's the weird bit...at first, they did.

We'll start with my PS3 at firmware version 2.01...

I began with disc 1 (obviously), using the Season Play feature...which does a lovely job of keeping track of your progress through the individual episodes. Finished disc 1 in a couple days, and moved on to disc 2. It gave me a bit of a hassle at first, but after a quick reset of the console (including shutting it off at the power supply, just in case), it worked fine. I watched the first two episodes of disc 2 that night.

I came home from work the next day, looking to enjoy at least one more episode. The disc wouldn't play.

More accurately, the disc played through the Buena Vista Home Ent. fanfare, and the copyright/commentary warnings. And then, it just stopped playing. Froze there for an eternity. I tried to exit playback mode. Still frozen for another couple of minutes. I turned off the system using the PS controller, and after giving me the error beeps, it shut itself down.

After several unsuccessful attempts with disc 2, I tried to go back to disc 1. Same story. Disc 3...no dice. Disc 4....5....6....well, you get the picture.

I figured it was part of the same problem that I was experiencing with Pirates, so knowing firmware 2.1 was coming, I waited.

Today, I downloaded and installed firmware 2.1 with no issues. You can probably guess what the first thing I did was...that's right, LOST disc 2 went straight into my BD drive.

That's when things got worse....

Now I no longer even get the Buena Vista fanfare. At least, not without some coaxing.

If I use the "Top Menu" button, those things play out. Then it gets past the copyright warnings...and freezes up again.

Now here's the really weird part. If, at this frozen juncture, I hit the Top Menu button again, the screen will flash this at me twice....

...and then go back to its original frozen state, from which I can repeat the process ad infinitum without ever reaching the menu.

For those of you astute enough to catch it, yes...that is in fact Johnny Depp as Captain Jack Sparrow with his face obscured by the FBI warning. I had disc 6 in, which has a preview for Pirates 3 on BD.

Anyone else having similar problems? Anyone who can offer a potential solution?
