Windows 7: Twinhan DVB card driver works in Vista 64bit but not 7 64bit HELP HELP

Twinhan DVB card driver works in Vista 64bit but not 7 64bit HELP HELP

I have a DVB card called Twinhan 1025

Twinhan company is gone so they dont provide new drivers

the driver we have is for Vista 64bit which works well with RAM more or less than 4 GB but in Windows 7 64bit it works with only RAM less than 4 GB

My RAM is 6 GB when I boot normally I am able to get the signal level and quality but cant add channels or view them

when I set the boot option the limits the memory to 4000MB I am able to view or add new channels

This is not a software issue
cause I have tried programs in compatibility mode and as administrator
and download viewers for 64bit OS and for 32 bit OS

So it's a driver problem or Windows 7 problem

Now can I do something to make Windows allow this driver to map specific range of memory ?

Please help with any solution cause the workaround of limiting the boot memory isn't a practical one

I even tried to install VM's and install Windows XP but they do not provide access to PCI slots
