The problem's not the program. First, you don't have such problems, because you tynner is USB, mine is PCI, and when I put more then 4GB RAM (and use 64 bit OS, so they all work) the tunner won't start. Nothing works, tried changing drivers, tried many programs, but nothing. And WinTV (except it's 6, that I use, because it's the one comming with the drivers) just hangs during splash screen, it's because it can't turn the tunner on. PCI-Express tunners don't have that problem, that's why I'm waiting for one to buy it
