Had this problem since had the box - 5 to 6 months. Have re-installed mytv3 as well as reset box and all software updates.
In the live TV section - there are many separate folders - Entertainment / Films / Docs etc - all the channels from (any) provider were being populated correctly in the appropriate folders.
On MOL3 it seems to pull out every channel and put every channel in a new folder, which is taken (created by sw) from the portal nickname - IE not a defined folder from the service provider?
Basically, it takes out all the channels and dumps it in a single folder, which the box seems to have created itself.
Thanks,
G
