tp134 is in our satelltes.xml as
<transponder frequency="11200000" symbol_rate="34285000" polarization="1" fec_inner="0" system="1" modulation="4" />
different modulation?
Currently in use: VU+ Duo 4K (2xFBC S2), VU+ Solo 4K (1xFBC S2), uClan Usytm 4K Ultimate (S2+T2), Octagon SF8008 (S2+T2), Zgemma H9.2H (S2+T2)

It is no longer DVB-S2X
the TBS 6983 ( only DVB-S2) card finds and reads this transponder now without any problem.
Only VLC still has problems to read the stream

need test on 45308X if work on AUTO or 16APSK

maybe HW bug on TBS69xx with ShortFrame
TBS5390 send correct stream

It is no longer DVB-S2X
PS: some sources state
16APSK FEC-3/4 FECFRAME-Normal as DVB-S2
and
16APSK FEC-3/4 FECFRAME-Short as DVB-S2X

Hello, what is the maximum data throughput of the AVL6261C?
DVB-S2/16APSK SR-31429 FEC-4/5 tests have started on Astra1 19 East, which gives a transponder data flow of 100 Mbit/s. The minimum C/N for this mod is 11 dB.

If you cannot find the correct specification of that chip, I would suggest doing some stress test with a STB that contains such a device.
I tested a 10 minutes full TS recording from a TBS 5580, tuned to that transponder (11817v31430) and the recorded content was free of errors.
I hope this helps.
Details of the test.
Recording made by EBSpro. Analysis by TS-Doctor 3.2
The TS contains 4 video streams with 4 audiotracks each (3x Mpg, 1 x Dolby E.
The program content is the same but with differend encodings and bitrates.
Track 1 min bitrate 4,2 max 19,6 average 14-17 Mbit
Track 1, 2, 3 min 3,8 max 11,9 average 9-10 Mbit
Hence the payload is about 45% of the transponder capacity, the rest is stuffing.

Another box on the same antenna - https://forums.openp...t/#entry1559724
That's why I asked about the maximum throughput, i don't care about the bitrate of the program.
Some boxes can process such high data after correcting the drivers or firmware
