Rtaxron - My wife suggested only watching Australian DVDs so you've a similar sense of humour!
wildwood - Too much watching Ricky Gervais, methinks!
squarebear - was about to try this, but...
...pauln90 - that worked! Fantastic! Incidentally it works with or without a DVD inserted, I've since found.
The mode button has to be depressed for approximately 3 seconds. Some accidental pressing by my daughter that was!
Another question now : any suitable actions recommended against 7 year old fibbers???
