Didn't help, unfortunately - mythtvsetup still complains:

2012-05-13 17:25:32.385665 E  FE_GET_INFO ioctl failed

The backend says:

dvb-fe-tol says:

# dvb-fe-tool
Device Sony CXD2820R (/dev/dvb/adapter0/frontend0) capabilities:
        CAN_2G_MODULATION CAN_FEC_1_2 CAN_FEC_2_3 CAN_FEC_3_4 CAN_FEC_5_6

CAN_QAM_256 CAN_QAM_AUTO CAN_QPSK CAN_TRANSMISSION_MODE_AUTO
DVB API Version 5.5, Current v5 delivery system: DVBC/ANNEX_A
Supported delivery systems: DVBT DVBT2 [DVBC/ANNEX_A]

...so the card should be set to DVB-C already, or at least a variant of
DVB-C. Is it possible that the kernel module simply doesn't understand the
v3 API? Or is v5 backwards compatible?
