My installation went fine. I start plugin --- do a search -- and videos appear to choose from. I choose one and video seems at is is about to start playing -- but screen stays black. Below, the video appears to be caching (purple line is moving) -- but screen stays black. I think that my problem is that I disabled Mplayer as the default video player in Canola (I didn't think that mplayer showed videos that I downloaded as smoothly as the default player). Perhaps mplayer needs to be the default video player. My question is .. . what are the instructions to reenable Mplayer as the default video player in Canola? I can't find the post that tought me how to make the change. Can someone let me know how to reenable Mplayer as the default player in Canola? Thanks.
