I have a Bravia KDL43W755C. After scanning two satellites I have several thousand programmes. I need to go through these to delete and reorder them, but the built-in functionality (I'm being kind and diplomatic here) is severely lacking in this department.

I discovered a piece of software called Sony Editor, but this requires the programme list to be transfered to a USB drive. Even with an empty USB drive inserted into the TV, the "Programme List Transfer" option in the Satellite/Technical menu is greyed out. Why is this and what can be done to enable it?
