They are handled exactly the same. There are reports of people having problems online with these cards and Hauppauge are giving people a download with a program to change the tuner to "LNA mode" some alternate tuning mode, does anyone know what this LNA mode is? Do the linux tuners support it? I'm going to find a machine to put windows onto and install this card and test it with the windows driver and the LNA utility and see if it make a difference. > > What does make a difference is that the PVR500 splits the antenna > signal internally and so requires a better quality signal.

Well, This banding occurs on a good quality signal too, even on a 30cm bit of coax from an RF Modulator on a Satellite receiver. I put an attenuator in line and it just made the picture fuzzier and still have banding. I have ordered another card to test to see if the one I have is just broken.
Have hauppauge changed to using the Philips instead of the Samsung, vica versa, different ones in different areas for PAL/NTSC or just whatever is cheapest on the day they order a batch to be manufactured? > > You could try to capture from the composite or S-Video input, this > bypasses the tuner circuitry and should give completely identical > results for the PVR150 and PVR500. Pretty much, yes, arguably marginally better on the 150 still, but not enough different that I could say this with certainty, and certainly no extreme banding like I see when RF Tuned.
