Looks like it's better to rebuild the box in the week and save wasting your time. After patching etc, I did manage to get a little bit further, but when using dvbscan I got an error: [root@cos6 bin]# dvbscan /usr/share/dvb/dvb-t/uk-Hannington > /home/mythtv/channels.conf Unable to query frontend status Dmesg output: usb 1-3: new high speed USB device using ehci_hcd and address 2 usb 1-3: New USB device found, idVendor=2040, idProduct=7080 usb 1-3: New USB device strings: Mfr=1, Product=2, SerialNumber=3 usb 1-3: Product: myTV.t usb 1-3: Manufacturer: Eskape Labs usb 1-3: SerialNumber: 4030928317 usb 1-3: configuration #1 chosen from 1 choice WARNING: You are using an experimental version of the media stack.
