No way, really. The good news is: If you order from Amazon, you have 30 days to make a return and exchange. Save your receipt and your box. When you get the unit, you ideally want to see something earlier than June 2004 on the back of the unit itself. If you do, you're set. If you don't, you return it as a defective item and get an exchange for another one and hopefully you hit gold that time.
Again, none of this matters at all if you don't care about using component upconversion.
