Often there are technical limitations on what you can do with DVD's, on-line videos etc.
Two examples:
Such limitations are typically introduced by the companies behind the media players in cooperation with the movie and recording industry. They are usually not based on legislation, and because of that you probably do not need to respect them. (Read more about this in k3b).
We have installed the media playser mPlayer with necessary codecs on this CD. With mPlayer you can watch all sorts of DVD's, on-line videos etc. without technical limitations.
Using the program mEncoder
you will even be able to save what you have seen or heard in
mPlayer. Unfortunately, the is yet no graphical interface for mEncoder, but if you open a terminal window, it is easy to download any
video stream with this comand:
mencoder -o FILENAME -oac copy -ovc copy
LINK
This will save the video stream LINK in the file FILENAME.
