DVB-T problems with em28xx chipset

Hi,

The device is a Pinnacle Hybrid Pro 330e (2304:0226). After a long and troublesome search and some dead links I found the v4l-experimental branch, compiled its modules and loaded em2880-dvb.

dmesg output:

Has anybody made the device work?

Analog TV is no problem with kdetv (but is with tvtime), but DVB does not function ...
