Windows 7 Trouble Recording Internet TV with Windows Media Player 12 on Windows 7

Using W7, Home premium 64bit.
I have a problem with certain "controls" in my WMP 12, in that I am not able to record a programme running on Internet TV. This was possible when I had XP and WMP - I think, 10.
It is also not shown in my Control Panel, but appears in my programme Files.
Would I be advised to remove it and download another version, if this is possible?
I have had a look at Windows Downloads and cannot find any availability to download it. The only information is that it is included with my Windows version.
I therefore would not like to remove it and not be able to replace it!
Any advice would be gratefuly received.

Thank you

Colin.
