after a software download you may find your recordings will not play.they are there in the menu but do not run in the preview screen.i was told by top-up/tv that if they are not in the screen, you will have to format the drive.Not always so,go to main menu,press 4-setup,press 6 help,then press the green button & try the yellow button,SOFTWARE REVERT,if it appears on the screen.this has worked for me,not always,but theres nothing lost if you have to format anyway.
