I had to do that as well when playing with OuterNet, PI and tevii usb. After putting that firmware in the folder Bam it worked

There you go Michael!
Vlc dvblast may be something to explore as well in the quest to build something AWESOME
I have an Android satellite STB that uses TVheadend. It works but it is clunky and would be confusing to the average user to configure. It is set up more for European use too with lots of cardshare and CA stuff in the backend that is just about impossible to get rid of. Overall the way things are setup are more for European type fixed satellite lists rather than hobby blindscanning and messing around like many do on this side of the pond. It is about as friendly (unfriendly) as E2 is for most Americans.
Advantages of Tvheadend is the HTSP makes sharing a full satellite list and controlling from another device almost as simple as DLNA. Tvheadend also supports a variety of S2, T/T2 and even ATSC tuners.
After messing with it myself I'd recommend only using it as a last resort or for experimentation. Much nicer back end options out there.

a PC's main objective; to move the most data across a network wire; while using the LNBf in dual polarity; or full one polarity; singled.
This spectrum is North America, and shows in a analyzer as one polarity or both if dual feed. Old days, it was 2x500MHz (which today is 1 gig); it could be doubled if re-placed with new hybrid typical just in C Band. So if you max out at say 100 MHz banded; your missing the point. The network must have single channel control to keep the wires ability to send and receive; cable headend. But that is not the objective. It then requires; say 5 network wires at the dish; and that is not the objective.
One coax to the "headend"; that is a DVB-S 300 mips receiver them days; without a computer; and the rasberry pi 2 is certainly built with memory and multi-cores (fastness). DVB-S, linux machine/os; files in files; and dnr files?; outputs w/o asi which is the time/control/feature (to flip skins). At being able to single channel feed, the selected channel outputs itself to the 10/100 as the stream; and multi-channels of that could be arranged into the browsed list. The fitting would single "progression" effective; and depend on the network/works it is running over (fast or mini-phone). It is when it starts getting effective at say a T2 or T1 spread out across a City or 2 that the monocular visit lie about. Mainly because then the only a few cable companies need what they should get (and there are very few of these; compared to sticking with a few). But if only netforks and doodoo are the only "boxed up" religion. I will continue to watch hdtv.
In all fairness; the internet itself is to say now how well each part of the network is working. This high power is just waiting to be challenged; headon! The multi-tuner of any (say 9) or multi/multi tuner (or loop out) 9X is not very costy; local cable started out with 10-20; then to 35 and more. Keeping it on a local frontend would also keep the network "fair"; as you will be well known. If you knew how many neighbors ;; bought a big dish from over the fence; you would be surprised.
One channel at a time is easier; but on the end of a headend is a hdtv (and large cables 1 gig glassed. This requires the ; and node re-haul , additional (or stb); only avail(multi-plex)able at per household amounts; to MATV or SMatv forget it ;; and almost the market you need ;; (catv today uses this "glass" they run for their "amps") of the many techs that went to node status (or use it for digital audio) also a single board and coaxed. This multi (pic/sound) is a display sized problem ;; which depends on what scale bumps the roadhouses run into (and tuning at the dish is a little scaled already)
just put it into a lnbf; pick it up w/o a wire; then over the internet; how many dishes are there left; probably 10,000...

Besides doing a little testing of the Pi2 hardware and memory, I have been doing some research and trying to decide where to start.
I ordered the TBS 5922. The TBS 5980 has the same chipsets as the non-existant Prof 7500 apparently but the only place I can find one
is a low rated Amazon seller. Read the one review, pretty bad and funny!
So I figure on the Pi you will need a piece of software that talks to the tuner and presents a stream for the player.
I was playing around with some of the prepackaged media centers but wallyhts got me thinking
in a different direction. And I also have a wild idea of building an IP-LNBF of sorts at the same time
consisting of a tuner and PI out at the dish sans coax. The coax run distances alone in my house, nevermind the runs out to the dishes,
would make you cringe, its a wonder I get a signal at all!
I had a brainstorm on how to power the thing by simply using power over the coax that already runs out to the dish. Just like the powered multiswitches use. The Pi runs at 5V and the 5922 runs higher. I will run the higher voltage out to the dish and regulate it down to 5V for the PI.
Anyway I researched two interesting and similar pieces of software, Dvblast and Mumudvb.
Both are available through apt-get on the PI and source code.
Dvblast is multicast only, and to install as a service you must write all the necessary scripts
https://github.com/gfto/dvblast/blob/master/README
http://www.videolan.org/projects/dvblast.html
Mumudvb will do unicast http as well as multicast
The mumudvb package also installs the service scripts.
Install through apt-get do a couple of config files
then service mumudvb start
http://www.mumudvb.net/doc/mumudvb-1.7.3/README.html
http://www.mumudvb.net/
For my initial test, once my tuner arrives, I will be trying mumudvb in http unicast mode.
Example of 4 channel setup:
Channel 1 http://10.0.0.1:5001
Channel 2 http://10.0.0.1:5002
Channel 3 http://10.0.0.1:5003
Channel 4 http://10.0.0.1:5004
There are other options such as channel by number and channel by sid.
http://10.0.0.1:4242/bynumber/3
http://10.0.0.1:4242/bysid/100
It can also generate m3u playlists.
Initially the client will probably be VLC on a laptop.
You could also use one of the media centers and tie the url to a channel source I would think.
Once I get everything configured and working properly on the "tuner" PI,
I will take my second PI and build a STB. The STB will basically just use a player to make an http connection to the tuner and
simply go to the next url to change the channel. I will build everything on the bench first and will attempt
to run the tuner/STB player all on the same unit to check performance for those interested in building an all in one unit.

Thank you Fred555 for all of the links and research!
I also purchased a TBS5922 a Tevii S662 and Geniatech for testing on the Pi2. The TBS and Tevii arrived yesterday and I plan on first configuring the Pi2 as a server then as a standalone STB. Have the Pi2 with 7" touchscreen and powered USB 3.0 hub set-up on the bench and several microSDs loaded with different OS.
Been playing with XBMC with a SiliconDust ATSC LAN based tuner as I waited for the USB tuners to arrive. Easy to tune and watch, but definitely need a DVR app and EPG for it to see any use at my home! Sure is a great media device!
The end of the week will try loading UpdateDVB on Linux. Need to do a lot of reading before attempting this! Not sure which tuner to try first...
Now that the parts are arriving I am anxious to start some projects!

Another must have would be to figure out some sort of signal strength indicator visible on the player. And also on the 5922 I have read you have to disable the ir sensor at boot or else it will continually try to decode ambient light, waste cpu and get hot and crash. Some have used black tape but there is a module.conf entry documented out there for this.

Sure would make it a lot easier if that 5922 box had an Ethernet port instead of USB. It could be modified to use POE (Power over ethernet).
That would definitely have a lot less voltage loss per meter than CAT 5.
Anyway, I'm wondering how hard it would be to modify an existing ethernet to USB converter for this purpose? Then you could have your Pi indoors and use it for the server. Maybe something to explore.
Below is a photo of the ethernet to USB converter that I use for my Mac laptop. It's smaller than it looks in the photo. If you guys are interested, I could crack the case on it and post a photo to see what chips are inside.
You can tell by the plug that is a usb device as is the 5922. You can only connect USB devices to USB hosts.
You could throw the RPI directly on the tuner, it's a host. Again it's getting the power to it.
Kinda looks cool having it all in one. Esp if you put a WiFi adapter in the RPI. Now you supply power and the entire thing is wireless minus the power.
There are pico power atx adapters that are super small. Like basically built into the atx plug small. These will supply the 5v and 12v required.
