Hi Kulbir Saini,
I've install videocache-1.6-1 on my fedora, but seemed metacafe did not working properly. I try to log request from metacafe and seemed they has move the content from v.mccont.com to akmccvideos.metacafe.com (or maybe they have 2 host to store the content?). Take alook at this sample below
I also would like to request feature to cache www.tube8.com. I attach you the log that hopefuly will help you to create the pattern.
acl videocache_allow_url url_regex -i [a-z]*[0-9]*\.tube8\.com/(.*)\.(flv|3gp)
