I tried a TBS6910SE tuner card today, the intent was that we could receive ABC's new DVB-S2X signal. I had to remove an existing card to make room for the new one so I removed one that was connected to a disk pointed at Galaxy 19 at 97° and also to a second C-band dish pointed at another satellite. The first problem is that Tvheadend doesn't seem to have any settings for DVB-S2X, so I tried using DVB-S2, but also it doesn't have a setting for the 25/36 FEC now used by ABC. I did find that if you start with 2/3 and backspace to the 2 you can enter 25/36 using the keyboard but I have no idea if Tvheadend actually used that setting. Anyway after updating the TBS drivers to the latest versions, Tvheadend could detect the card was there but it simply did not receive any signal on it, at least not for ABC.
So I tried the other dish connected to the other tuner. Also no go. Tried swapping the tuner networks and settings in case TBS reversed the position of tuner 1 and tuner 2 on the card. Still nothing. Tried installing dvblast; it could detect the card was there but could not receive a signal on it (and yes I did disable the tuners in Tvheadend first so there was no conflict). Tried dvblast on another mux through a different card and it showed the signals available on that mux with no problem. So it was not just Tvheadend that could not communicate with the card beyond recognizing that it existed, dvblast couldn't do anything with it either.
So for anyone thinking maybe you can use a TBS6910SE to receive ABC, unless you are a Linux expert that can diagnose exactly why a piece of hardware isn't working, be careful. It is always possible I got a defective card, but then again I also didn't realize that Tvheadend doesn't have settings for DVB-S2X nor for the 25/36 FEC. But that would not explain why the second tuner would not pick up a very standard DVB-S2 signal using 5/6 FEC that we've been receiving for years, and that the old tuner card picks up with no problem whatsoever. This is one of those situations where is could be a defective card, bad drivers, something weird in Ubuntu server, or probably any number of things I have not considered (nor would even know enough to consider). But I am just saying that if you think you are going to swap out an older TBS card and put in a new TBS6910SE and it will just work with Tvheadend (or maybe anything else under Linux), I fear you may be as disappointed as I was.
