PS3 Disc Auto-Start

[Steve]

Since one of the more recent firmware updates, my PS3 (backward compatible 80 GB model) won't automatically play a disc any more. It was going by default to the "what's new" under the PSN network icon. I did a search for this issue and read about turning off the "what's new" feature. I did that, but now every time I power on my PS3 by sliding a blu-ray disc into it, it defaults to the "playstation store" under the game icon. I've checked and double-checked and disc auto-start is set to "on". Could someone please advise how to get the auto-start to start working again. I did a search for this, but the only thing I found was what I posted above about turning the "what's new" feature off. Thanks to anyone who can help.

And by the way, I do have the most recent firmware installed.
