“search plugins” does not seem to work

Hi… I am trying to search for a media player plugin. I already have Yendif Player and want something similar. I have logged into to the ww.wp.xz.cn in both Firefox and Chrome and when I go to the plugins section…no matter what term I enter into “search plugins” I get no matches. I even entered Yendif and it returned no matches for that. Also when I go to the plugins area the start page show popular, featured, etc plugins… but when I click on “see all” it stays on that same page… and there doesn’t appear to be any page link numbers to click on the bring up any other pages. Am I doing something wrong? Thanks for any help!!
