Firstly, let me apologise if this is not an appropriate place to ask what is not really a development question... I have been playing around with the Hauppauge WinTV Duet dual USB tuner today. dmesg seems happy when it is connected, and detects it as two devices This: http://www.linuxtv.org/wiki/index.php/Hauppauge_WinTV-Duet-HD-Stick Suggests the device may be supported, though the "HD" vestion does not seem to exist as far as I can tell. I can run "scan" to get a channels list from the device no problem, and whilst VLC will not play from it, tzap works fine. Using mplayer I can access either tuner - but not both at once - so: mplayer "dvb://0@" works, as does mplayer "dvb://1@", but not both together, which whichever is second giving: ERROR OPENING FRONTEND DEVICE /dev/dvb/adapter0/frontend0: ERRNO 16 DVB_SET_CHANNEL2, COULDN'T OPEN DEVICES OF CARD: 0, EXIT ERROR, COULDN'T SET CHANNEL 0: Failed to open dvb://1@. dmesg reveals: [ 17.402977] DiB0070: successfully identified [ 17.402984] dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.
