Play3 download

Hi To All

I haven’t been burning movies for very long but I’ve never had a problem when wanting to do so. Lately everytime I try to burn a movie it comes up with an error stating that I have to downloadPlay3w.com to be able to watch or burn the movie. Can anyone tell me what exactly is this download and do I need to do this to enable me to continue on.

Thanx for anyones help.
