I would also like to know. I am getting a USB tuner for Christmas, and I was looking at the express card tuners, but there weren't many. How is the quality for each?

I would say the express tunners as they attached to the PCI-E Express bus. I would try and get some reviews before you buy though.

Well, just a guess here, but since it's the tuner that does the work, I would guess the bus it's attached to is not of much importance since the signal will be compressed after it has gone through the tuner. The bitrate of that signal is quite low compared to the speed of the usb bus or the expresscard bus, so I don't think one is better than the other.

Somebody correct me if I'm wrong.

480 Mb/s for USB transfer and 2.5 Gb/s for PCI Express, so theoretically, the express cards can offer better quality then the USB.

Heres some more info if you want to read more

Sure, but what's the typical bandwidth of a video signal? a fraction of the USB and the expresscard transfer rates, so does it really make a difference?

Not trying to be an a$$, just trying to know!
