Is there any way to know from looking at the packaging whether you have a good or bad set? I just bought it at Best Buy for $19.99 and I cannot tell if this is part of the old stock. I've read somewhere that next to the UPC symbol, you'll find an R2 for the good one. Mine does not have this. I know that if I open it, BB won't let me return it.

Thanks,

You might want to check the thread Back to the Future Rerelease which is exactly one thread above this one.

It has been determined elsewhere that if you got in on the $19.99 sale of BTTF Trilogy, you are in possession of the corrected discs. Fret not.
