The ~stoth/hg/s2 has no DVB-T support on the HVR4000 yet. Those patches 
will appear very shortly in ~stoth/hg/s2-mfe.

I'm speculating that your issue is the same issue I fixed sometime ago 
(2-3 months in the master repo). I'd suggest you wait for the 
~stoth/hg/s2-mfe patches to appear later tonight and test again.

That tree (and ~stoth/hg/s2 for that matter) have the i2c fix I'm 
referring to.
