over the past months I had some fun in watching chess videos trying to learn from the Grandmasters (even bought some ChessBase videos).
But you can also find a lot on youtube. Here are some links to Rybka videos (I do not know if they were given previously here or somewhere else):
I would recommend the first one by kingscrusher dealing with one of the games Rybka vs. Zappa in Mexico. Generally this strong player from England has a lot of interesting videos to offer with mainly GM games where he checks his analyses and comments with Rybka.
Below the link to all 239 videos so far by kingscrusher:
