No difference between the 2 remotes you posted from Amazon.
A while back I saw some cheap Xbox 1st party remotes on ebay for about 10 or 15(with the shipping). Now, you say how could they afford to offer them so cheap? A while back MS gave away the remote free with the system, so that's how.
As far as DVD playback, I think the PS2 suits me just fine. Not the greatest(no zoom feature what-so-ever), but 1 less machine.
I loved the DVD playback of the Xbox. It has zoom, faster rewind/fast forward and some other things I can't thing of right now.
