As requested by some of you - I attach a updated version of the plugin MegaVideoPlayer.
I have not tested any film to the end. But videos work ok.
Important :- Megavideo videos (and films) cannot be streamed directly. Must be downloaded first.
The method :-
(1) Configure video type, movie type and cache folder path. The saved videos will be in folder /cache folder/megavideo.
Also : configure "Stop download at Exit from plugin" - Yes/No
Requires gst-plugin-flv in the image.
