So has anyone able to get the Proof 7500 to work with this project successfully?

The Proff-7500 is capable of doing DSS, however apparently the windows drivers corrupt the stream. However the stream is not corrupted in Linux, but the problem is that the software required to handle the streams require TSREADER, a Windows program. 
   It is possible to record the stream on linux and then feed the recording into TSREADER on Windows.

Yeah that is what I thought I was able to get all the TP's using the Proof 7500 from off 101, TSReader.jpg  but it would never populate.

Are you running the DSS2DVB plugin with TSreader?

Yup I am agreeing with what WeJones said, this Proof 7500 won't do it, I have try every which way, did someone posted a listed of cards that are KNOWN to work yet?

For DSS
I think anything that has the STV090X based or STV091X based demod

Here's crazycats Sourceforge link that helps to at least get a list of cards.
You might have to ask crazycat to make  sure if there are others.
https://sourceforge.net/p/crazyscan/wiki/Info/

Then a few posts back jodaesca mentioned TBS8920

Now I don't have that card but maybe someone will come along and say for sure.
Or crazycat would know.
But I did find some specs listed here at the linux tv and it says direct tv (dss)

I don't think it's quite that simple.  The Prof 7500 and the TBS 5925 are STV09X examples, of cards that the specs say should work, but they apparently have Windows drivers that corrupt the stream.  And my TBS6983 is an example of a STV091X that doesn't have DSS capability, and won't even lock.  And my TBS5927 is a STV091X that will lock, but have the corrupted stream issue. 
  My TBS6925s are examples of STV09X that will work.
   The Prof 7301 is a question mark....  There have been posts that say it works, and  posts that say that it didn't.  Anyway, I wouldn't trust any card to work in Windows unless you see posts saying that it does work.  On the other hand, as I posted, the Prof7500 doesn't work in Windows, but it does work in Linux, but you need a way to get the stream over to Windows in order to use the TCP_DSS source and TSREADER, unless Iboston's software makes it possible to bypass the use of TSREADER, in which case getting a cheap Raspberry Pi, and a USB receiver like the 7500 to feed Iboston's software might be an option.
  And although expensive and maybe no longer available, there is always the Genpix receivers and the STB that had an internal Genpix card (I forget the receiver's name).

I am still looking for a confirm list of satellite cards that work with this project, I see two posted but either one you can't find anywhere.

I guess sounds like, stay away from USB devices in windows for dss, Unless they can fix the driver.
With tbs 6903 with STV091X with crazyscan I have to select "directv" in the search standard box to get a lock
Thats Weird the older version 6983 won't lock dss.

  And just to add a piece of info, I did try selecting "directv" with the 6983, even though it was never necessary with the 6925.  Relative to the "stay away from USB" thing, that's what I had thought until I found that the Prof7500 would function in Linux. But there are some posts from Crazycat that suggested that there was a hardware issue with some USB receivers like the 5925 and 7500, so the drivers involved may be drivers for the usb hardware, perhaps in Windows.  So it may well be that when I posted that the Prof7500 functioned correctly in "Linux", perhaps I should have said that it functioned on the RPi, which may have different USB hardware or drivers.  Not sure if there are any Linux users on a regular PC to check out the 7500.  It may not work on a desktop PC.  It also makes me wonder if other cards that should be able to do DSS, like my 5520 and 5927 might work on computers with different USB hardware.  
  Also, when I said that Windows drivers "corrupt" the DSS stream, it's not just that it's been corrupted, like not being able to keep up, but that it has been changed, ie the 0x1d DSS sync bytes removed and replaced by 0x47 DVB sync bytes and the packet size changed from 131 to 188. Without knowing much about the DSS structure, it was hard to tell if the actual payload was still intact, however with the discovery yesterday that the DSS PID 0 was always the same, it might be possible to figure out exactly what Windows is doing to that stream, so maybe some C-programmer might be able to re-construct the stream.
   Anyway, there may still be a chance for currently available cards like the 5520 and 5927.

EDIT: I looked once again at the TBS5520, and from what I'm seeing now it is completely bogus data.  It shows a lock but doesn't ID as DSS, and I didn't run into any 0x1d sync bytes that were followed by the proper bytes, and were often much more than even 188 bytes apart, not just 131. Even if it is deleting bytes while searching for sync 47 bytes, you would still expect at least 1 0x1d every 188 byte packet, so the data must be completely bogus.
   So I conclude that TBS5520 must not do DSS at all, and I don't know where it's data is coming from.
ALSO, it only locked when I specified either auto/turbo/or DCII.  Wouldn't lock in any other mode. So DSS must have more in common with those modes than DVB/DVBS2??

Fellow Members, your posts are welcome here! Do not worry about posting everything perfect. Different receivers and LNB's will give you different Frequencies and Symbol Rates. Some set top boxes, PCI cards and USB receivers, Do Not Require all of the same information that others may need. It is not Required to post everything that others may need to tune in a feed. It is just most important to share the find. We can always adjust the Frequency and Symbol Rates and try the various Modulations and FEC's on our own receivers until we get a lock and then give a polite reply with what works for your receiver, as that information might help others as well. We all appreciate the efforts and energy of the Posters!
