From memory Mikey Bs image has the softcam set up but you need to add your own newcamd.list and mg_cfg file. There are example files in the folder. If you have saved your newcamd.list and mg_cfg file all you need to do ftp them over to the /usr/keys/ folder. Once you have done that just press the remote buttons: blue > softcam > sofcam panel > make sure your "select cam 1"has mgcamd_1.38r1 showing (if its not press the right arrow key until it does) > green button to re-start and the channels should clear.
If you havent saved your own files go to post 242
