downloading movies
 

I downloaded a movie but I can't watch it. It shows that is was downloaded in full but when I hit "launch" I don't get anything. Can someone help.
Thank you.

Did you look at the Sticky at the top of this section? It already has your answer sitting there. What you need is codecs. Get GSpot which will tell you which codec you need. Also get VLC (in-built codecs) as a backup player at least. VLC is very reliable for previewing. CODECs list and alternate players for Movies
