Definitely not affiliated with this site. You should be cautious about getting plugins like that. Many are disguised malware. Hopefully you had your shields on (antivirus and antispyware) and they didn’t spot anything amiss.
A lot of the time, videos that require plug-ins or executables or activex controls just try to get you to download malware. Many times they’re not even videos (or don’t have any video contents in them)! If in doubt, use a diagnostic utility like one listed in this thread to find out what’s in the file. If it turns out to be a fake, then just get a different version.
