Ah damnit I'm in a pissy mood. TV tuner works fine in my other computer, just not in the one I want to use it.
I've tried changing video card (Nvidia to ATI), didn't do it.
I tried removing my Creative X-Fi, didn't do it.
I tried changing PCIe 1x ports, didn't do it.
I tried XP 32bit instead of Vista 64bit, didn't do it.
I tried around 5 drivers for the TV tuner, didn't do it.
This is really becoming a hardware issue... The problem I experience...
