Ripping from a firewire camera under Linux
To automatically split scenes, with no limit on file size:
dvgrab --autosplit --size 0
If your NLVE software auto-splits scenes then you do not want dvgrab to do it for you; remove --autosplit.
Speaking of NLVE software, I use Kino version 0.7.x (GTK2 version), and find it to be excellent. Nice work.
