I load just dvb-core.o dec2000_frontend.o and dvb-ttusb-dec.o

I'm pretty new to it myself, unfortunately, and I've not played with any dvb 
apps except for tzap.

If you get a kernel panic, then it's not your fault, but a bug in the code.  
If you don't require a dvb net interface, try playing with tzap from the 
linux-dvb pre-release tarball.  Hopefully I'll get a chance to look at fixing 
the problem soon.
