Consistently scrolling in netflix on iPod touch.

Hi I've got the netflix app on my iPod touch, and over all it seems pretty good in terms of accessibility. I'm curious, however, what exactly the deal is with scrolling while browsing through films in sub genre lists. I've read the guide on here, and it works, though only 2-3 movies are swapped out. I did figure out that a 3-finger horizontal swipe makes the pages scroll in some way if I move by element (one-finger swiping), though I'm unsure of exactly how many titles are swapped out. In conclusion I guess what I'm asking is: have you guys figured out a use for the 3-finger left and right-swipe? Because it definitely does something. Or do you still like to interact by direct touch and pushing the strips? Sorry if this seems confusing, but hopefully my point comes across. Malthe
