Doesn't work :(
Here's how it goes for something like
dvgrab - | mencoder -nocache file.mpeg -

Or, if I enable cache in mencoder, nothing gets recorded at all,
although dvgrab appears to work OK. When I press Ctrl-C I get

"stdout": buffer underrun near: timecode 00:08:32.23 date 2007.03.08

This error means that the frames could not be written fast enough.

from dvgrab.
