I can't really recommend anything as you're not in the UK! Much (some?) of what is on sale here will work in Europe but I don't know of anything for sure. Both my terrestrial PVRs have options in the installation menus for other countries but, obviously I haven't tried them.
A media player is higher spec than a simple PVR and will cost accordingly as it's basically a small form computer and will have a DVD drive as well as a hard drive.
All I can say is that I bought both my PVRs off Ebay. My first was over three or four years ago. It's a Digimate label but made by the huge Turkish Vestel corporation that makes stuff across a very wide range for many small and not so small names (Google Vestel and you'll see). It was an early model that cost me abot £35 or so I think as it was ex-display (but turned out to be brand new). It's served me well over the years but I've nearly filled the small (80Gb) hard disk up. I bought my second only a few weeks ago with dual DVB-T2 tuners so that I can get Freeview HD. I still haven't used it all that much as I can already get HD throught the Humax HDR PVR that I also have!
Anyway, I'm waffling. Can I suggest you try Ebay Es and put whatever translates as tv recorder or hard disk recorder in as a search item? 320Gb is a bit small if you're recordinh HD programmes, but fine for SD only. For HD go for 500Gb or 1Tb.
