Agreed—this feature is ALWAYS broken. You can see a few more items recently aired if you click into the "Watch QVC2 TV" link and scroll down below the live feed window, but the lack of up-to-date product listings where they're supposed to be is frustrating. Miraculously, as soon as a show on Q2 ends, all of its contents appear for browsing, but while the show is on, there's just one item in the list.
ETA: The fact that this virtually never happens with recently aired items from shows on the main channel makes it seem even more odd...
