I'm currently in release mode and just released GNOME DVB Daemon 0.1.12, the third release in three weeks. Those three releases include an improved DBus API, a way to assign channels to any number of groups and a lot of bug fixes. You can configure the channel groups in gnome-dvb-control from the "Edit -> Channel Lists" menu. Unfortunately, the groups are not yet displayed in Totem (coming in the next release). Currently, only the DVB Daemon plugin in Coherence makes use of it. You can download the tarball over at Launchpad.
In addition, the incredible Sebastian Reichel created a Debian package of GNOME DVB Daemon. I'm sure the new release will show up there soon as well.
