I've noticed some serious problems with my TBS6925 when analyzing very high bitrate transponders (e.g. 23,E 12645H, 12685H, 12725H all DVB-S2, 30000, 8psk, 8/9)
Though SNR seems to be good the BER sporadically jumps to bad values. This results in ts_packet discontinuities and wrong ts_packets. Another card (Prof 7500) doesn't count any errors at al. The BER always stays at 0.
Can somebody check these transponders? I suspect a possible hardware fault.
