A few weeks ago when DVBLogic released the Release Candidate of DVBLink 4 they slipped in Boxee support into the build, today they have made available the Boxee client. You can get it by browsing to the DVBLink repository from the Boxee repository browser (dvblogic.com/boxee), with the app you can browse the EPG and watch live TV from the box.
Don’t forget you will need DVBLink 4 RC1 or higher for it to work.
