I have two btxxx tuners installed. One is a Pixelview clone and the
other is an Askey. They both run off the same aerial which is split
into 3 (1 goes to the TV). When watching Live TV one of the cards
shows a good picture quality on all channels, but when I switch to the
other tuner by pressing "Y" some of the channels are good but some are
awful quality. How can that be when it's the same v4l driver, same
aerial feed, same channel details in channel setup etc? Could it be a
problem with the aerial splitter?

Two cards, most likely two different tuner types. They've got two different locations inside the computer case (different interference induced). In short, lots of possible problems.

If they're *identical* cards with *identical* tuners, then I'd start looking at cabling oddities.
