Need help with TV tuner decision

[max347]

I have been searching around, googling several things, but have yet to come up with an answer. I need a TV tuner for a laptop, but am not sure what would give me good image quality. It seems that even usb 2.0 throttles some image quality? Is PCMCIA an option? I have found several pcmcia cards, but am not sure if the interface would be more advantageous or not.

I would like something that would be analog/digital inclusive. Does anyone have any pertinent info, or even some recommendations? The laptop is running xp pro. Thanks, Max
