Yes, that I have understood. But from the threads on the MythTV lists below, it seems at least one user has one or more 290e sticks running fine in DVB-T (or T2) mode.

At least for me. It was some time since I actually ran it. I'll have to try again tomorrow as the backend is currently recording, and MythTV seems to tie up the device even though it is not connected with any input in mythtvsetup... > > >> After trying dvb-fe-tool to force the card to DVB-C: >> >> ---- begin cut ---- >> >> Didn't help, unfortunately - mythtvsetup still complains: >> >> 2012-05-13 17:25:32.385665 E FE_GET_INFO ioctl failed >> (/dev/dvb/adapter0/frontend0) >> eno: No such device (19) > > > I looked frontend code and I do not see where that error is coming. > Maybe there is no such file at all? The file is there, as seen in the ls output I posted. And dvb-fe-tool complains when mythbackend is running: # dvb-fe-tool Device or resource busy while opening /dev/dvb/adapter0/frontend0 # lsusb ...

The system also has a Hauppauhe PVR350 and a Hauppage Nova-T 500, in case that's relevant. The Nova works fine, although the reception is poor (70%) which is why I got the 290e for DVB-C. :) BTW, I see firmware being loaded for the Hauppauge devices. Is the same needed for the PCTV 290e? >> 2012-05-13 17:25:33.865334 E FE_GET_INFO ioctl failed >> (/dev/dvb/adapter_290e/frontend0) eno: No such device (19) > > > "/adapter_290e/" something unusual. It's created by my udev rules: # Create a symlink to the DVB-C tuners of the PCTV 290e SUBSYSTEM=="dvb", ATTRS{manufacturer}=="PCTV Systems", ATTRS{product}=="PCTV 290e", ATTRS{serial}=="00000006LG6C",\ PROGRAM="/bin/sh -c 'K=%k; K=$${K#dvb}; printf dvb/adapter_290e/%%s $${K#*.}'",\ SYMLINK+="%c" I use this since I have multiple DVB devices which can move around at reboot, which confuses mythbackend somewhat. :) > > >> The backend says: >> >> 2012-05-13 17:33:23.922804 I [9042/9059] TVRecEvent tv_rec.cpp:1014 >> (HandleStateChange) - TVRec(24): Changing from None to WatchingLiveTV >> 2012-05-13 17:33:23.926627 I [9042/9059] TVRecEvent tv_rec.cpp:3456 >> (TuningCheckForHWChange) - TVRec(24): HW Tuner: 24->24 >> 2012-05-13 17:33:23.960061 N [9042/9042] CoreContext >> autoexpire.cpp:263 (CalcParams) - AutoExpire: CalcParams(): Max >> required Free Space: 2.0 GB w/freq: 14 min >> 2012-05-13 17:33:24.171394 E [9042/9164] DVBRead >> dvbstreamhandler.cpp:626 (Open) - >> PIDInfo(/dev/dvb/adapter_290e/frontend0): Failed to set TS filter (pid >> 0x0) >> >> >> 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_FEC_7_8 CAN_FEC_AUTO CAN_GUARD_INTERVAL_AUTO >> CAN_HIERARCHY_AUTO CAN_INVERSION_AUTO CAN_MUTE_TS CAN_QAM_16 >> CAN_QAM_32 CAN_QAM_64 CAN_QAM_128 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.
