This seems to fix the problem of not being able to lock DVB-S2 after locking DVB-S2 MIS/PLS -

However there are still problems with the MIS/PLS signal itself, I'm still getting missing/corrupt TS packets for the Rai multiplexes on 5°W (e.g. 11013 V 35300 ROOT+16416 MIS 3 as above). The SNR level of 9.7dB should be more than enough for perfect lock of DVB-S2 8PSK 2/3 which only requires 6.6dB. These also worked perfectly on the TBS6905.
I'm still wondering if the hardware itself in my device might be faulty?
