A very strange thing

I'm tryng to install two azbox premium. The first one it's an old premium the second one it's a premium +. I'v a dual feed dish. I can't receive the astra's signal. With the old one I can receive Hotbird channels. I've already an old, but very strong, clarketech 2100 (the oldest version). The clarketech STB can receive both satellite. Obs I've checked all settings. All STBs are disecq 1.1 with hotbird on 1 and astra on 2. Did anyone have this problem and did he solved it ? Thank you very much !

Thanks I'll try it. I'm sorry I forgot to say that the firmware on both stbs is 0.9.5309 (it's more and more very strange)

Very good guess Ted47 :thum:
I erased all channels DTT included. Then I used Disecq 1.0 and cherged the new list. Very good. Thank you ! :appl
