Thanks for your response.

I was basing the "better" remote off of reviews I have personally read. I own the BD-390 player and its remote is on the flimsy side.

To clarify, in the past I have observed people doing the same thing I am asking to do which is use a such and such remote for such-and-such version of a product, which was designed for another version of the product. I just haven't seen other people talk about using the newer 5xx series remote with the older 3xx series players is all.

I was merely stating that I know from observation that for certain devices this has been possible; but I didn't know if it was possible for my device.

I live in the USA. I will try the links you gave me. Thank you!
