So now my riders are stuck listening to what I want to hear or choosing to watch a DVD or TV tuner while going to Vegas.

And using the other perfectly-good ways to locate music on the player aren't available to your riders?

Not to say that there's not a bug or anything. I mean, I never use PINs, so I wouldn't know if it had gotten broken in a recent release.

My only question is: If you downgrade to 1.03, do the PINs start working again?

Or, more accurately, when did you notice that they stopped working?

I don't know how many digits they are limited to, but if you think there is a limit to the digits, you can do some experimenting to find out where that limit is.
