Hi, Ive got the same problem.
I've just phoned up the helpline and hae been told to try the following:-
Menu
4 for set up
6 for help
press keys 1, 3, 9, 7
scroll down to option 7 - disable library video window
right arrow key - change to yes
Press library button
Hi-lite the file causing the trouble
Blue button
Green button
After a few seconds it should delete
