Hi, I've been trying to use the Portuguese DVB-T transmissions. These are h264 unencrypted transmissions. I bought an Asus My Cinema U3100 mini, which seems to be correctly recognized by the dib0700 driver in Ubuntu 10.04 (kernel 2.6.32-22-generic). I can try the latest upstream kernel to see if anything has changed. From the dmesg:
[ 2118.910130] usb 1-3: new high speed USB device using ehci_hcd and address 6 [ 2119.061233] usb 1-3: configuration #1 chosen from 1 choice [ 2119.062384] dvb-usb: found a 'ASUS My Cinema U3100 Mini DVBT Tuner' in cold state, will try to load a firmware [ 2119.062396] usb 1-3: firmware: requesting dvb-usb-dib0700-1.20.fw [ 2119.066293] dvb-usb: downloading firmware from file 'dvb-usb-dib0700-1.20.fw' [ 2119.273034] dib0700: firmware started successfully.

[ 2120.247732] dvb-usb: ASUS My Cinema U3100 Mini DVBT Tuner successfully initialized and connected. The messages talk about MPEG2 so I don't know if there is anything in the driver that doesn't work with MPEG4/h264. dvb-apps doesn't include a scan file for Portugal but the relevant line seems to be: T 842000000 8MHz 2/3 1/2 QAM64 8k 1/4 NONE # RTP1, RTP2, SIC, TVI This should work for almost everywhere except in the Azores islands where several frequencies are used. I can submit a full set of files to be included with dvb-apps. Scanning doesn't usually work: $ scan /usr/share/dvb/dvb-t/pt-Porto -v -o zap > channels.conf scanning /usr/share/dvb/dvb-t/pt-Porto using '/dev/dvb/adapter0/frontend0' and '/dev/dvb/adapter0/demux0' initial transponder 842000000 0 2 1 3 1 3 0 >>> tune to: >>> 842000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_1_2:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_4:HIERARCHY_NONE >>> tuning status == 0x1b WARNING: filter timeout pid 0x0011 WARNING: filter timeout pid 0x0000 WARNING: filter timeout pid 0x0010 dumping lists (0 services) Done. There was however one time where it did work. I though it was because I had set fec_lo to 1/2 where before was NONE but after a reboot it stopped working again. The time it did work it generated the following channels.conf: RTP 1:842000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_1_2:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_4:HIERARCHY_NONE:256:257:1101 RTP 2:842000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_1_2:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_4:HIERARCHY_NONE:512:513:1102 SIC:842000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_1_2:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_4:HIERARCHY_NONE:768:769:1103 TVI:842000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_1_2:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_4:HIERARCHY_NONE:1024:1025:1104 HD:842000000:INVERSION_AUTO:BANDWIDTH_8_MHZ:FEC_2_3:FEC_1_2:QAM_64:TRANSMISSION_MODE_8K:GUARD_INTERVAL_1_4:HIERARCHY_NONE:3840:3841:1111 Using vlc and either this channels.conf or just tuning to 842Mhz directly no sound or image is obtained and continuous error messages like these come out: libdvbpsi error (PSI decoder): TS discontinuity (received 6, expected 1) for PID 0 Using mplayer produces a similar result: dvb_streaming_read, attempt N. 6 failed with errno 0 when reading 1484 bytes Any ideas on how to get this working?
