Hello, Thank you. Meanwhile I've contacted TBS and support told me that they have their windows driver working (in lab) with multi PLP. For now they don't want touching the Linux driver with that same modification because they wait confirmation on the field that the Windows driver is working. I'm not in Russia now therefore I can't confirm for them that their windows driver works with a real life DVB-T2 broadcast... I will maybe have an access in Tomsk but I'm not sure yet if there is DVB-T2 broadcast with a multi PLP there... Eventually, is there somebody in Russia under a DVB-T2 multi PLP broadcast range?
