I don't know if the graphics card you are using supports video decoding acceleration and if skype can make use of it, but at least here with the ati binary blob, I can only get video decoding acceleration for one video stream at a time, trying to decode 2 videos at the same time with video decoding acceleration results in a hard crash. I have never tried with skype and currently I'm using the free drivers so I have no way to test this. If this is true for your case it should be quite easy to reproduce.
It might have been just a random crash caused by skype too, since it isn't the most stable piece of software you can use.
Thanks for this valuable advice again. I tested it, and indeed, when I turn on another video, the system locks up after a while (not immediately though).
