Squirel try these i gurantee these will work if not something is wrong + check your cable that your getting signal from - i have to fiddle mine about to get a better connection sometimes (dont know why its not asif the wires is cut or anything)
First of all uninstall everything todo with compro bar dvd player (its rather good dont you think for free?
)
Then install this one
FIRSThttp://www.comprousa.com/downloadfiles/T300Driver1330.zip
That file is like a bios file for the card - but is software
SECONDLY Install this one.

This is the software (obviously)
They make tiny updates but on their website they dont change the name (its always compro dtv 2.5 but they always make tiny changes to it)
Now save these on your hard drive (reason i say this is because they released some really good drivers a few months back, but they changed them and the stability went way down and I coouldnt find the old drivers anywhere)
When you install it do you do it properly? I.E when it does scan for channels do you choose the right one? i think its digital tv or attenta tv or something.
Have you also checked that you have a digital tv aerial - an outdoor one? I had a really old tv antenna that came with the house - although it receieved analogue signal it didnt digital - so i found a guy that gave me a brand new tv antenna right outside my bedroom fitted it and everything and checked it worked for £60!

There you can find members of this trusted union or whatever it is and it also has a list of rogue traders!
If your aerial is right and your cabling is right and you installed like i said there should be no reason this wont work - hope you get it to work mate because i wouldnt dream of having my pc without this tv card in it now.
