Page 1 of Wharfedale 750/750S Differences

Ive recently by mistake purchased a Wharfedale 750 from Tescos, when what I really wanted was a 750S.
I would like to know what I have to gain from taking it back and changing it for a 750S, if theres IS any reason at all.
Its got a DTS logo on the front of the machine, and it plays my CD-R`s fine, so is there anything to gain from me getting the latest model?
Obviously I want to be able to play ANY region DVD, and also the RCE ones. I believe from reading this site that this version of the 750 is ok for this, and is region hackable from the remote. But there only seems to be a `any region` hack, not a `specific 1/2 region hack` , is there a drawback to this at all?

Thanks in advance for the help, I believe I have 14 days if i want to change it, so a thorough response would be appreciated.
Thanks again, and merry christmas to everyone.

I gather that most people have had sucess with Gladiator Disk 2 on the 750S where as 750 owners are the ones generally reporting the problems

Which I guess would mean that the 750S has more system memory as I read that was what is causing the problem with gladiator disk 2 in the 750

Feel free to correct me if im wrong folks!
