Mythtv 0.26 is Broken in Ubuntu 13.04 amd64 Desktop!!!

[Singapore Citizen Mr. Teo En Ming (Zhang Enming)]

Hi,

I have recently purchased Intel Core i5-4430 3.0 GHz processor, Asrock 
B85M Pro4 LGA1150 motherboard, 8GB Kingston DDR3-1600 memory and Cooler 
Master Elite 311 ATX casing on 4th July 2013 for SGD$501.

Then I installed the latest Ubuntu 13.04 amd64 desktop. I have also 
installed Mythtv 0.26 using the following command:

sudo apt-get install mythtv

teo-en-ming at intel-core-i5-4430-desktop:~$ mythbackend --version
Please attach all output as a file in bug reports.
MythTV Version : v0.26.0-37-g340b5d4
MythTV Branch : fixes/0.26
Network Protocol : 75

using_vdpau using_ffmpeg_threads using_live using_mheg using_libass 
using_libxml2

When I tried to scan for TV channels, mythtv-setup.real reports:

Failed to find any new channels!

Note that I am using mythtv-setup.real to configure my Hauppage WinTV 
PVR USB2 TV tuner, not mythtv-setup. If I use mythtv-setup, a black 
blank MythTV Setup Terminal screen will pop-up and nothing happens after 
that. I have configured everything correctly in mythtv-setup.real.

Hence I conclude that MythTV 0.26 and TV channel scanning are BROKEN in 
Ubuntu 13.04. Previously when I use Ubuntu 11.10, MythTV was working 
wonderfully.

To overcome this problem in Ubuntu 13.04, I have installed Oracle VM 
VirtualBox. Then I installed Ubuntu 11.10 amd64 as a VirtualBox virtual 
machine. Then I installed MythTV in Ubuntu 11.10 amd64 virtual machine. 
Then I use USB Passthrough to passthrough my Hauppage Win TV PVR USB2 to 
my Ubuntu 11.10 virtual machine to enable me to watch TV in a virtual 
machine!!!

I am wondering if developers could fix the MythTV TV channel scanning 
issue in Ubuntu 13.04. Please also let me know if there are any 
workarounds or solutions to this MythTV 0.26 problem in Ubuntu 13.04.

Thank you very much.
