OK so that didn't work. This is exactly what I have done.
1 Clean install of OpenATV 5.1 Image - latest build dated 10 Dec 2015
2. Gone through the Wizard, language, display, tuned both tuners, changed Screen position a bit
3. Initialised HDD and Created Swap file
4. Installed Plugins
FlashExpander and setup to use external HDD
Cacheflush and configured to do a silent flush every 15 minutes - also did a clean now
EPG data importer - xmltvimport and xmltvimport-rytec and completed that.
Autobouquetsmaker - done that and go all my sly channels and FTA
FTPd Slyk Skin IPK
FTPd TS Panel IPK
Enabled new Skin - Rebooted box.
5. Went to TS Panel
Went to Soft Cams Icon
Pressed Blue button to install and installed mgcamd 1.38
FTPd my keys across to a now populated user/keys folder. This folder was empty before I installed mgcamd, but now contains: priority.list, replace.list, SoftCam.Key and the two files I just copied mg_cfg and newcamd.list.
Pressed green button to stop / restart Mgcamd - This was stopped before this point.
And still I get the "No ecm info" message in the middle of the screen
Backed up the extra 3 files and removed them from the usr/keys folder to leave just my mg_cfg and newcamd.list files. Green button again, no change. Restarted box no change.
I am stumped. So tomorrow I will backup my image and try a pre-built image and see if that makes sense adding my keys.
Thanks for all of your help people tonight.
