See, as I said, way over my head, and it shows, hee hee.
Last programming classes I took were in the early '80's. Back then we had Basic, Pascal, Fortran, SAS. Those must be Smithsonian ready.
Im currently in the field right now, the army has been keeping me busy this year.
Basically reboot or plug in your DVB device, fire up updateDVB. Go to file - settings and configure your lnb. Save and close that dialogue. Then do a direction l spectrum scan, click on a tp you want to tune. A tuning dialog will open up, it'll parse the tp. From there you can do what you wish with it, play, steam etc

It says go to Kit options and configure a compiler,No luck with GCC.

That is very Cool, I would not have thought Cozi was that strong in relation to the others.
Updated instructions for installing Ubuntu for ARM and installing updateDVB on your pi2
After Fred555 and I went through and got Updatelee's software working we made some changes along the way. Mostly it is just clarifying some of the steps to make it easier for someone who has no or very little experience with Linux. Updatelee you are more than welcome to comment on anything you see you don't like and I will change it.
Note anything with a # sign in front of it, is just comments or instructions to read, not what you actually type into your command line.

Code:
#Getting the image onto SD
#Method 1, Needs a linux box with card reader
# download http://master.dl.sourceforge.net/pr...te-15.04-desktop-armhf-raspberry-pi-2.img.bz2
# install ddrescue
sudo apt-get install ddrescue
# extract downloaded file
bunzip2 ubuntu-mate-15.04-desktop-armhf-raspberry-pi-2.img.bz2
# write to microSD, mine mounts on /dev/sdb, yours may be different
sudo ddrescue -d -D --force ubuntu-mate-15.04-desktop-armhf-raspberry-pi-2.img /dev/sdb
# now resize the RPi2 image on the microSD using gparted
sudo apt-get install gparted
sudo gparted
#Method 2, Uses a windows machine to write image and RPi2 to expand image:
Use 7zip to extract the ubuntu mate image on a Windows machine.
Use Win32diskimager to write the disk to SD as usual.
Insert the SD card into the Pi and boot the Ubuntu image and go through the setup routine.
Manually resizing the SD card on Raspberry Pi
fdisk /dev/mmcblk0
Then delete partitions with d and create a new with n. You can view the existing table with p.
p to see the current start of the main partition
d, 2 to delete the main partition
n p 2 to create a new primary partition, next you need to enter the start of the old main partition and then the size (enter for complete SD card). The main
partition on the Debian image from 2012-04-19 starts at 157696, but the start of your partition might be different. Check the p output!
w write the new partition table
Now you need to reboot:
shutdown -r now
After the reboot you need to resize the filesystem on the partition. The resize2fs command will resize your filesystem to the new size from the changed partition
table.
resize2fs /dev/mmcblk0p2
This will take a few minutes, depending on the size and speed of your SD card.
When it is done, you can check the new size with:
df -h
# edit your /boot/config.txt if you want (optional) I add
arm_freq=1000
sdram_freq=500
core_freq=500
over_voltage=2
initial_turbo=30
# Also add any mpeg licences to your config.txt if you've bought them, like mpeg2 (recommended)
# update your repository
sudo apt-get update
sudo apt-get upgrade
sudo apt-get dist-upgrade
sudo apt-get autoremove
sudo reboot
# install some pre-req's

# There is a bug in one of the qwt headers installed from apt-get, so lets fix that
wget http://svn.code.sf.net/p/qwt/code/branches/qwt-6.1/src/qwt_transform.h
cp qwt_transform.h /usr/include/qwt/qwt_transform.h
# To download the updateDVB source
git clone https://bitbucket.org/updatelee/updatedvb.git
#This will create a directory called updatedvb and will contain the source code.
# open qtcreator
qtcreator -noload Welcome
Then Open a project and browse to the updatedvb directory and
open updateDVB.pro
Go to:
Tools, Options, Build and Run, Compilers
Add Gcc if it is not there, then click apply
Now click on Kits and make it look like this:
http://www.satelliteguys.us/xen/media/kits.129/
Click Apply and OK
# To compile hit the green triangle in the lower left that says 'Build and Run'
Build should run for a little while and updatedvb window will pop up.
Exit out.
Go to one directory above the updatedvb directory.
You should fing a directory named: build-updateDVB-Desktop-Debug
cd into this directory and you will fin the executbl you just compiled called updateDVB.
Now lets get it to your desktop so its handy:
cp updateDVB /home/<your username>/Desktop
Hook up your tuner and double click the updateDVB icon on your desktop.
Go into settings menu and setup lnb, diseqc etc.

Note on SD card size for Ubuntu Mate and UpdateDVB
We used an 8GB card for this. We had to delete zip files after unzipping and cleaned up uneeded files along the way
and at the end we were at about 80% capacity. Something to consider before starting. A 16GB SD or larger
may be needed depending on what else you want to load on the Pi.
