Given it's a BDP-series player, if you were interested you may be able to get a Linux shell of some kind on it and find out what's taking so long to run on it.

There's a whole lot of Phillips and Sony players that are based off some ancient Mediatek SDK.

Edit: Wow, that's old: Sigmatek, not Mediatek. A makefile in the GPL source suggests there's a similar Pioneer player somewhere, too.
