Hello, i just get an Starsat SRX50CU with USB, but i have problem with DMC15 package, i'm getting black screen with an ok audio, the codec for DMC15 is on Cryptoworks / DMC15 and is correct because the same code i have on another receiver and work good.

but the problem is funny, i turn all dmc code in 00 00 00 00 00 00 00 00 and i'm still getting Audio on all channels like E! Reality Zone etc,

you know, if you change one number from correct code the channel lost, but not audio on my DMC15 at telestar

what's going on with my receiver, have the cryptoworks problem on my receiver or what? anyone can help me please?
thanks in advance.
