I am using the Hauppauge Nova-T-500 and there are working well for me and i am in Perth/Australia
Hope this helps
Thanks hgait - very helpful. Fingers crossed it works for me too! EDIT:
Oh wait - this is a PCI card not PCIe correct? As I have had issues with 2 cards already via PCI (that should work) I'm going to try PCIe (PCI Express) as a last hope...
