Thanks for the pointer.  Someone introduced a logic bug that didn't show up right away.  It was creating an invalid offset for the ZRANGE as you suspected.

Fixed.

Eric maybe I found a bug with the new implementation: apparently in the category page the first page is always empty, with just the four videos people are watching right now, but without the big listing.
From page 2 everything starts to look ok again.
Maybe related to the parameters passed to ZRANGE?

Cheers,
Salvatore
