"Plays" attribute doesn't change

Hi

I am using the Kaltura Client Library (PHP) with KalturaCE to show my entries. I want to show the attribute "plays" and "rank" with

$entry["plays"];
$entry["rank"];

I can see the rank "value" but the "plays" value is not showed. When I play a video, the "plays" value doesn't change. I can see this value in my kaltura database ('entry' table) and using the Kaltura Management Console, but is always 0. I have tried this with the Kaltura Hosted Edition (with free account) and I have the same results.

It is working in Kaltura Community Version?

Thanks
