I have just switched two N lines from CCcam and i'm
running them in MG Cam, they seem to run better.
One for cable and one for sat.
You could always try this too
Open or make a completely blank newcamd.list file,
paste into the file both lines, directly underneath each other, ftp to box.
As mentioned above your n line will start "CWS = " in Mg Cam
and "N : " in CCcam
