There are people working in a mod tuner for dreambox. Rules do note allow link so I will quote.
"The new tuner is programmable and allows the end user to flash it with code (just like you can flash the receiver firmware). I guess this is how Wizard is coding it to open up powervu channels. I believe the legal application of this tuner is for transport stream upgrades to process exotic signals like 4.2.2, 4.4.2, 4.4.4 and whatever else. I am not a coder, but the way I understand it, coders can flash whatever they want to the tuner which will allow them to manipulate the raw satellite stream in any way they like. "
Another option. So, now that there is vplug it opens the posibility for Test on stb's. Vplug can be run under a server. Then you just connet your stb to your server. Just search in this forum for "vplug sblc" or "vplug fausto". There are other server wrapers available.
Now please note that there mayor reasons as for why most receiver will not get you a good picture. But there is no reason as for why you can not try it and learn in the process. Most likely you will end up been able to decode for the key, but as the other PC alternatives you will not have a picture, due to the DES vs CSA video encoding diference. Good luck.
