I've had this model for just over a year now but recently noticed what appears to be a *faulty* recording *stuck* on the HDD. Whenever the offending recording, which incidentally is only 33 seconds long, is accessed, the machine freezes and then crashes to a green screen and goes into standby of it's own accord. I can access other HDD recordings fine. I'm on F/W Ver 3.06. Any ideas please?
