I've just tried adding one of these tuners as a 3rd tuner on my freestanding backend (running Mythbuntu 0.22 on Karmic with Avenard repositories). According to <a href="http://www.linuxtv.org/wiki/index.php/DVB-T_USB_Devices">http://www.linuxtv.org/wiki/index.php/DVB-T_USB_Devices</a> this device should work out of the box with kernel support since 2.6.28 (I'm on 2.6.31-16-generic). It seems to be being recognised and the required drivers seem to be present (the files dvb-usb-dib0700-1.20.fw and xc3028-v27.fw are present in /lib/firmware. dmesg shows the following during startup (this was taken during a startup with my 2 existing tuners removed (both Winfast DTV-2000H PCI cards).<br>
<br>[ 27.329939] dib0700: loaded with support for 9 different device-types<br>[ 27.330223] dvb-usb: found a 'Gigabyte U8000-RH' in warm state.<br>[ 27.330273] dvb-usb: will pass the complete MPEG2 transport stream to the software demuxer.<br>

When I go into capture cards I am able to find a DiBcom 7000PC DVB capture card which I install. I then go to Input connections and select this card. I enter a Display Name (Tuner 1) and select the EIT as my Video Source. I then select Scan for channels and start a scan with my usual settings (Desired Services = TV, Only Free checked, Test Decryptability unchecked, Scan Type = Full Scan, Country = Australia). I then start the scan and I get the scanning screen but nothing happens. If I try to cancel or stop the scan, the backend setup crashes and I have to kill it. The next time I run backend setup it will crash fairly readily until I delete this tuner and start all over again.<br>
<br>Does anyone have any ideas what is happening here. One thing that concerns me is that the box is labelled as U8000 ver 2.0. I haven't seen any references to the 2.0 online so far. However lsusb returns<br><br>Bus 001 Device 002: ID 1044:7002 Chu Yuen Enterprise Co., Ltd<br>
<br>which is the same as is listed on the linuxtv wiki.<br><br>Any ideas? Thanks.<br>
