Hello!

I am about to buy Strong 4652 stb with a DVB-C tuner.
I intend to use it with my local cable provider that uses Nagra enc. system. I see in formware section that there are already some firmwares to insert keys to use with it right?
What should i use to place my provider keys out there? I've got them.

Also, there are some channels in my provider that only have AC-3 audio pids. Does the Strong chipset convert this kind of audio to analog output? or i'll have to use optical output?

Thank you very much!
