Just did a fresh install on my powermac, and just for the hell of it I tried to share my itunes library from my powerbook. I think all the music is there, but not all the videos are showing up. example: I have a bunch of "the office" episodes, but only 4 of them are showing up..actually, now that I look, it seems only 4 of other shows are showing up too. Is this a limitation of itunes? If so, it sucks.
