Piping / redirection error in dvgrab 3.0-1

Binary package hint: dvgrab

Piping and redirecting does not work in dvgrab 3.0:

dvgrab - > file.raw
dvgrab -f dv2 - | mplayer -cache 2048 -
dvgrab -f dv2 movie.avi | mplayer -cache 2048 -
dvgrab -f hdv movie.avi | mplayer -cache 2048 -

This works though:
dvgrab -f hdv - | mplayer -cache 2048 -

This is a known problem, fixed in version 3.1 (dec 9, 2007).
From the ChangeLog of ver 3.1:
