How to Watch Freesat HD on Mythtv 0.22 Linux PVR with Ubuntu

This article focus on the installation of DVBs/DVB-S MythTV DVR/PVR system and the software. In this guide, I will show you how to setup of the MythTV software and get it working with your DVB s2card.
The Setup
When you setup of the MythTV, please make sure that our mouse will not be able to point and click at the MythTV buttons. MythTV was designed with a TV mindset from day one, so it’s expecting inputs from a remote control. In this case, your keyboard works just fine. The keys you are going to use are:INSERT KEYS HERE
Verify DVB s2 card is operating in Linux
Before starting this process its worth checking your DVB s2 card is correctly recognized by the Linux Kernel. Open a Terminal window (Applications->Accessories->Terminal) and do the following, this would  show your card is Linux supported TV card.

Start MythTV-Setup
To begin the setup process, you need to run mythtv-setup. From the menu at the top of your screen, click System->Administration->MythTV Backend Setup. This should fire up the setup process and present you with the initial language selection screen. Select your language, verify your network settings and press enter to bring up the 5 option main setup menu. If you get a ‘no UPNP backend’ error, please verify your network settings. Go into option 1, General.
This should now bring up some networking parameters. If you followed Part 1 of this howto, using ‘apt-get’ to install MythTV, then the MySQL DB and network information should already be filled in for you and you only need to select a PIN (set the PIN to 0000 to disable it. The PIN is not really necessary unless you want to stop other people on your home network from watching TV and recordings), then <TAB> to select the ‘Next’ button at the bottom right of your screen.
On the other hand, if you installed MythTV and MySQL yourself without using apt-get, then input the parameters you set up with here, set your PIN to 0000 then <TAB> to ‘Next’ at the bottom right of your screen. Mine looks like this (Note PIN is not shown in this picture, but you still need to enter it):
On the next screens you should modify the values as specified below. Any values not specified here can be left at the default values. Don’t forget to <TAB> to ‘Next’ after each screen :
Locale Settings screen
* Format = ‘PAL’
* VBI = ‘None’
* Channel Frequency = ‘Europe West’
Misc Settings screen

* Master backend override = ticked
* Delete files slowly = ticked
* HD rungbuffer = 9400
EIT scan options screen
* EIT transport timeout = 1 minute
* Cross source EIT = ticked
* this is useful if you add more sat orbital positions later on)
* Backend idle before EIT = 30 secs,
shutdown/wakeup screen
No changes, leave the default values
backend wakeup screen
No changes, leave the default values
Backend Control screen
No changes, leave the default values
Job Queue (backend specific) screen,
* Max jobs = 2
* Job queue check = 300 seconds.
* If your mythbox is on all night long, set the job queue start and end to the middle of the night when you are asleep so MythTV jobs do not hinder your daytime system performance. For example, start 02:00 end 07:00.
* cpu use =  medium
* Allow commercial detect = ticked
* Transcoding = ticked
Job Queue (Global) screen, Job Queue (Job commands) screen, UPNP Server settings screen
No changes, leave the default values.
On the UPNP Server settings screen, the ‘Next’ button should be replaced with ‘Finish.’ <TAB> to finish and select to return you to the main setup menu.
DVB s2 card Setup
Select menu option 2 (capture video cards) then click new capture card. Set Capture card type to ‘DVB DTV capture card (v3.x)’ NOTE:  your card may show up as V4L or similar initially. Make sure you select DVB DTV capture card instead. Once selected, the system should auto fill technical details regarding your card, such as type.
* Set tuning timeout to 20000 and signal timeout to 20000
* Select the Diseqc settings button (even if you dont use it). In the new window, hit enter on ‘unconnected’ (Note you may need to press the right arrow key on the word ‘unconnected’ to highlight/select it before hitting enter). This should bring up a menu, from which you select LNB. This will bring up another window, where you set ‘LNB preset’ to ‘universal(europe)’ – this is assuming you have a European style universal LNB (Sky minidish has this). Select finish (you should now be back one page and see ‘LNB’ instead of ‘unconnected’). Hit escape to take you back to the card setup screen
* Select recording options and in the new screen set max recordings to ’2′ (this allows you to watch one channel and record another if they are on the same DTV transponder/multiplex). Tick wait for SEQ start header. Untick open Mythtv supported card on demand. Tick use DVB s2 card for active EIT. Put a ‘tuning delay’ of 100ms to help with Budget DVB cards. Select finish to go back one screen, then select finish again
You should now be at the capture card list and you should see your card, like so:
If you see the DVB S2 card on the list, Hit ESC to go back to the main menu. Congratulations, you have successfully completed Part 2 of this guide and are well on the way to watching Freesat TV on Linux Ubuntu.

How to Use TBS6925 watch satellite TV with XBMC and MythTV


To watch satellite TV on your PC with XBMC and MythTV, you'll need at least one satellite TV tuner card or a satellite provider that offers satellite IPTV access. That Linux TV card hardware doesn't have to be installed on the same computer on which you want to watch HDTV. We'll call the computer with the tuner hardware the backend. The computer used to view TV will be called the frontend. The backend and frontend can be one and the same machine. XBMC will be run on the frontend on linux

TBS6925 PCI-E DVB-S2 Card is a new released professional satellite TV tuner card, which is regarded as one of the best TV tuner card for Mythtv or linux. This mythtv TV card can capture 16 APSK and 32APSK Demodulator. It also supports CCM, VCM, and ACM mode at the same time. The key feature is that TBS 6925 can receiver multiple Transport Stream and Generic Stream .it even can support up to 190 Mbit/s channel bit rate capture. TBS has updated Linux tv tuner drivers which supports all kernels up to 2.6.38, which enable users to freely watch or record HD FTA satellite with XBMC and MythTV in Linux, especially the HD Mediaset channels

As far as we know, XBMC currently supports the following backends:
  1. HTS Tvheadend
  2. VDR
  3. MythTV
  4. MediaPortal
  5. ForTheRecord
So, if you want to run the TV card on Linux, You'll have to install (at least) one of them.

Set up MythTV on Linux
1.    Set up your TV tuner card as DVB type in mythtv-setup's. On the capture card setup page, you will see a button called "DiSEqC." Highlight it and press enter. Start with a blank screen and the word "(Unconnected)." Highlight "(Unconnected)" and press enter. You will see a list of DVB hardware myth can manage. Select "Switch."




6.    Escape out to the top Mythtv-setup menu. Enter the "4.Input connections" menu. Highlight your TBS6925 card and press Enter. You will see a screen unique to DiSEqC setup. Select the DiSEqC switch port with the LNB we are setting up (in the example, port 1).


8.    MythTV will default to the "Tuned Scan." You will need the transponder frequencies, polarities, and symbol rates for each transponder you wish to scan. If the scan fails, check your dish pointing and/or settings and try again. When the transponder has finished scanning, you can press "Back," and attempt a "Full Scan of Existing Transports" scan type.


Set up XBMC on Linux

XBMC Media Center includes a media source that can communicate with a MythTV backend using the Myth Protocol and MySQL database queries to the mythconverg database. This requires that the MythTV configuration is checked to ensure XBMC will be able to communicate with MythTV, which depends on whether XBMC is running on the same machine.

To communicate with a MythTV backend, add a new Source from the Videos section. The source should have a URL that looks like: myth://username:password@i.p.address This URL needs to be specified manually as many skins don't support the ability to configure a MythTV source.

When you select the newly added MythTV media source five folders will be listed:
  • All Recordings - to watch anything that has been recorded all in one folder.
  • Guide - to view the EPG for a channel
  • Live Channels - to display what is currently being aired
  • Movies - to list the movies that have been recorded
  • TV Shows - to list each series of TV shows that have been recorded

After choosing Live Channels a listing of the channels used by MythTV is displayed.

When a channel is chosen, the currently playing TV show on that channel is shown.

Note that channel changes can take some time depending on the DVB-S2 tuner card and configuration being used by MythTV.

Viewing the Electronic Program Guide (EPG)
After choosing Guide a listing of channels used by MythTV is shown.

When a channel is chosen, the listing of upcoming programs on that channel is displayed.

The last thing is to enjoy the HD satellite programs as you like. That is to say, TBS 6925 would be a perfect TV tuner card for Mythtv .You should never miss it.
