====== Backend ======

===== Intro =====

I bought this tuner card ([[http://www.newegg.com/product/product.aspx?Item=N82E16815116037| Hauppauge WinTV-HVR-2250 Dual TV Tuner / Encoder 1229 PCI-Express x1 Interface - OEM ]]) to put in my new atom based backend.  It doesn't seem to be as solid as a recorder as my Das Original Air2PC cards... BUT... we'll try again.

===== Install =====

==== Base ====

  - Fresh install of Mythbuntu 10.04 LTS wiping out the original.
    * Chose the primary backend
    * Enabled ALL services:  SAMBA, NFS, SSH, Mythtv
  - Update the packages to the latest and reboot
  - Install some programs I cannot live without:
    - jed:  <code> sudo apt-get install jed </code>

==== Configuration ====

  - Set the IP address to be static (help found [[http://www.howtogeek.com/howto/ubuntu/change-ubuntu-server-from-dhcp-to-a-static-ip-address/|here]]):  modify **/etc/network/interfaces** to reflect the local IP
    - remove the network manager stuff <code>
aptitude remove network-manager
</code>
    - remove the DHCP client:  <code>
sudo apt-get remove dhcp-client
</code>
    - set our IP address to what you want: <code>
# The primary network interface                                                 
auto eth0                                                                       
iface eth0 inet static                                                          
        address xx.xx.xx.xx
        netmask 255.255.255.0                                                   
        network xx.xx.xx.xx                                                   
        broadcast xx.xx.xx.255                                               
        gateway xx.xx.xx.1                                                   
        # dns-* options are implemented by the resolvconf package, if installed 
        dns-nameservers xx.xx.xx.xx                            
        dns-search some.domain.com
</code>

==== Re-Install Drivers ====

Since every time I rebooted, mythtv claimed there was no active tuner... so, again, did this:   --- //[[david@lattice.net|David Lloyd Rabine]] 2010/09/19 22:31//

  - Remove the installed firmware:  <code>
sudo rm /lib/firmware/*.fw
</code>
  - Repeat the above procedure
  - Run the mythtv backend setup
    - Remove all tuners
    - Add new tuners (find each DVB device and add it)
    - Connect the "local tv" stations to each tuner card and set the default channel to 2_1
  - Reboot

==== Backend Configuration ====

  * General
    * [Page 1] IP Address to xx.xx.xx.xx
    * [Page 1] Master backend IP address to same xx.xx.xx.xx
    * [Last Page] Automatically run mythfilldatabase
  * Capture Cards
    * New Capture Card -> DVB 0
    * New Capture Care -> DVB 1
  * Video Source
    * New Video Source
      * Video Source name: Local ATSC
      * Username:
      * Password:
      * PRESS Retrieve lineups and pull up our zip code channels
  * Input Connections
    * Connect each tuner to the video source
      * Scan for channels

====== Frontend ======

===== Basics =====

  - Installed Mythbuntu from CD making this computer just a "front end"
  - Enabled SSH
  - Left DHCP as I have my daemon giving out the proper IP based on MAC address


===== Configuration =====

  - Modified theme to the one I LIKE!
  - Modified ALSA mixer so that audio SPDIF is output 
    - Load up the mixer as root<code>
sudo alsamixer
</code>
    - Modify the line:  **Item: S/PDIF Output [Off]** with the 'M' key
    - Save your configuration with:  <code>
sudo alsactl store 0
</code>
  - Modified the Audio output to use S/PDIF:
    - Utilities / Setup -> Setup -> General -> Page 4
      - Speaker Configuration from **Stereo** to **5.1**
      - Upmix:  **Best**
      - Audio Processing Capabilities:  Check both **Dolby Digital** AND **DTS**
  - Set our VIDEO output to VDPAU:
    - Utilities / Setup -> TV Settings -> Playback -> Page 3/8
    - Current Video Playback Profile:VDPAU High Quality

==== Remote Control Configuration ====

I added the following lines to my **lirc** configuration:  **~/.lirc/mythtv**

<code>
### added by david rabine (dlr) 2009.12.28 ###

# I added the following - dlr 2008/10/18
# Skip forward (10 min default)
begin
    remote = Streamzap_PC_Remote
    prog = mythtv
    button = >>
    repeat = 0
    config = PgDown
    delay = 0
end

begin
    remote = Streamzap_PC_Remote
    prog = mythtv
    button = <<
    repeat = 0
    config = PgUp
    delay = 0
end

# Seek to previous commercial cut point
begin
    remote = Streamzap_PC_Remote
    prog = mythtv
    button = YELLOW
    repeat = 0
    config = Q
end

# Seek to next commercial cut point
begin
    remote = Streamzap_PC_Remote
    prog = mythtv
    button = BLUE
    repeat = 0
    config = Z
end
</code>

==== Media Library ====

=== Audio ===

  - Add in symbolic links to our libraries
  - Go to Listen to Music and it will scan for new files

=== Video ===

  - Add in symbolic links for all our shares / files
  - Go to Utilities / Setup -> Setup -> Media Settings -> Video Settings -> General Settings:  /var/lib/mythtv/video as Directories that hold videos

===== Trouble Shooting =====

  - The images were "tearing" with some High Definition content, found [[http://www.mythtv.org/wiki/VDPAU]] this page.  Not sure why disabling the composite output on the card fixes this, but it does.  <code>
sudo nvidia-xconfig --no-composite
</code>
