Hi Guy's I am fairly new to all of this and still having problems getting my DM 800 to read these so called keys. I have created a directory within /var named keys and ftp'd nagrarom7 in it, restarted the dreambox and when i tryed to select certain channels other than free view i could not load then to view. I then telnets onto the dream box cd into /var an the keys directory has been deleted. So i created a scce directory instead and ftp'd nagrarom7 into it restarted the dreambox an this has also been deleted. Any ideas

Hi Harpo,
I had a similar problem. check your camd settings and if they are still set to common interface. You need to download new cams off the gemini server.
start by pressing blue button. it says at top what camd. If already evocamd try restarting the camd (green). If not go into camd settings (1) and reload the list. If there is only common interface you need to download evocamd.
Let me know and I will tell you how.

thanks for explaination


There are two types of channel that are sent out by the cable company; FTA (free-to-air) and encrypted.
Free-to-air channels are basically freeview channels. You don't need to subscribe to a package to get these channels. If you use an image without an emu or keys you would still get these channels.
Encrypted channels are channels that the cable company want you to pay for. These channels are encrypted before being sent out and normally you would pay the cable company for a smartcard which you would slot into your recevicer and this will allow you to receive the encrypted channels. It's kinda like when you buy software and you get a key with it. You won't be able to use the software without knowing the key.
Keys are also included in the cable stream. Normally your digital smartcard will extract the keys from the stream and store them in memory. It would then use these keys to decrypt the channels when you flick through them. Since we don't use a smartcard with a dbox we need something else to decrypt the channels. This is where the softcam (also known as a cam or emulator (emu)) comes in. The box or image itself doesn't know what to do with the keys, it's the softcam that grabs the keys from the stream and stores them in a file (keylist.txt, Autoroll.key, Autoupdate.key). If the keys are changed by the cable company the softcam will update the keys stored in the file.
The enctytion that the cable company usesis called Nagra1. So we also need to include nagra rom files in our images. These go in /var/scce and /var/keys.
There are several different softcams that we can use; evocamd, mgcamd, newcamd & gbox. It doesn't really matter what one you use, they all do the same thing. Some emu won't work in certain areas or on certain providers so it's good there are alternatives. The emu can also cause problems with direct recording over ethernet so if you have a blocky recording, try changing the emu or the tuner driver.Comment

I have used the key updater by Winker and sent the "tw 04.12.08" keys to the box. All of the Fta channels are working yet none of the encrypted ones. What other files do I need to add? Oh and I have transfered the nagrom7.bin file to the /var/keys folder and disabled all rom except 7.
