Hi Jim,
you spotted a regression in the latest media_build release from
11/01/2012.
I had the same problem here:

"dvb_frontend_ioctl_legacy: doesn't know how to handle a DVBv3 call to
delivery system 0"

with 3 totally different sticks (em28xx, dvb-usb, as102).

Everything was working fine with media_build drivers from 08/01/2011, so
the problem originates from a patch committed in the last few days.

In fact, I reverted this patch:

http://patchwork.linuxtv.org/patch/9443/

and Kaffeine started working again with all my DVB-T sticks.

Best regards,
Gianluca
