php -r '
var_dump(preg_replace("#http:\/\/(www\.|)zshare\.net\/video\/([^\/]+)#Ui",
"\\2", "http://www.zshare.net/video/541070871c7a8d9c";));
'
string(16) "541070871c7a8d9c"
given the above test I don't see the problem with the regexp
(but you don't actually show the code so it's hard to tell), I'd
probably look else where for the char munching culprit.
