I have been in contact with technical support but they are no longer replying to my emails (at least not in a timely manner).

Please can someone advise me further?

Did you try Robo_Raver suggestion so that you can rule out win7 being the culprit

As Taras has said, what happens when you either re-install windows on a different hard disk (make sure the TV card is out of the computer when you install windows) or try it on a different PC ?

In my emails to technical support, I did mention that I have tried it on a friend's computer that runs windows 7. It works flawlessly.

But, if you are suggesting that it is down to my installation of windows 7, I haven't tried reinstalling windows. I will do that but as a last resort, however.

Have u tried resetting the bios dmi pool. On some bioses you have to manually reset it in bios.

The reason rob and I are suggesting a test win7 install is that is quite easy for things to go wrong in windows and sometimes the best way forward is to do a test clean install of windows to see if that cures the issue.
