Sony Channel Editor - removed channels still appearing

[geralltr]

I have attempted to use the Channel Editor to remove and reorder satellite channels. The file is stored correctly (I can open it again on the PC, from the USB, to check, and the new order continues to appear).

When I import into the TV, it says that the import is complete, I then remove the USB and click OK to restart - which it does... but then there is no change in the channel list!

Any advice?
