rsosa all the videos are really great quality but there is a problem i noticed, when I download your video on rapidshare, the video keeps shocking, like someone take a a bunch of pictures and put it together to a video, like these little freezes during the points, I noticed these problems on all of the videos you posted on rapidshare, but when you posted on Youtube, there are no freezing or shocking at all 
This is definitely not a problem with rapidshare. There are no changes within the files made. YouTube changes the files! Sosa encodes to an AVI-container, YouTube reencodes into an MP4/FLV-container. It think, that's the reason. As I mentioned before, AVC in an AVI-container can lead to playback issues, because an AVI-container is not made, to hold AVC, especially not with b-frames. You could use AVI-Mux GUI to extract/demux the video- and audio-stream. You will get a .h264 and a .mp3 file. Then open Yamb and create a mp4-file with this two streams, simply open and save. Then every program should cope fine with the video.

Sorry, to demux AND remux you have to use Yamb, not AVI-Mux GUI!
