Well, mine's on its way to Toshiba for servicing. It is locking up with every disc format including audio CDs. I upgraded the firmware and it still did it. So, I called their customer service and I guess I have to ship it to them (on my dime I might add) and they said they'll turn it around within 3 days and FedEx it back to me.
It really sucks because the picture quality is unbelievable and as a DVD upscaler this thing blows my Oppo out of the water. Oh well, in a week I'll have it back hopefully in tip-top shape.
