You can go to the video interface, to playlists and choose "add playlist". Then when you see a video, you just click "add to" under it and so you can choose into which playlist you want it to be added. This way you can feature any videos in that playlist. There can be different playlists, one for tutorials, one for trailers and one for each LP.
I will subscribe to that channel when it won't be empty, but I don't know how could it be used to full extent. Generally, such a channel would be for ZC, itself: news from devs, release announcements, etc...

CamStudio works OK for me so far, I use big windowed mode, select the area of the window and the recording is going. It's just that it creates only .AVI.
