BTW i don't know if your device has the same capability (full ts dump..): when i insert it on the USB BUS i get from dmesg: ========== [10511.327179] usb 2-2.2.3: new high speed USB device using ehci_hcd and address 15 [10511.346586] usb 2-2.2.3: configuration #1 chosen from 1 choice [10511.543120] DVB: registering new adapter (TerraTec/qanu USB2.0 Highspeed DVB-T Receiver) [10511.544594] usbcore: registered new interface driver cinergyT2 ========== and here it's a sample of a command line for dvbstream (you get La7 in Bologna) to dump the complete ts stream ================ andrea@nb-venturi:/opt$ dvbstream -f 714000 -o 8192 > /tmp/prova.ts dvbstream v0.6 - (C) Dave Chapman 2001-2004 Released under the GPL.
