Hi,
I have to agree with you Nick. It really pees me off that every season 1-4 box release has been issued in a different format, including packaging, menus, extras etc. And now to really take the pi**, I have found that "Universal" are about to release a 17 disc box set of seasons 1-4 for £47.99. Which means they have ripped us off on price as well. No doubt this box set will probably be in a uniform package so that it will look nice on the shelf, while our high priced individually purchased sets look odd. I have included a link below for anyone that's interested.
