In GridFlow, [#io.quicktimehw] (libquicktime) is the only module that can 
record video. You have to use it through the [#out] interface. It's 
available in all the Ubuntu packages, and in the latest OSX package 

There's nothing for writing sound in GridFlow. However, there's a fairly 
new feature of [#io.quicktimehw] for reading sound from a quicktime, which 
is available through [#in~] as signals or through [#in] as grids. It's 
still a bit experimental though.

([#in~] is just a simple combination of [#in] with [#to~])

It's very possible that I replace libquicktime with something else (but 
patches would stay compatible, apart from use of the name "quicktimehw")
