Just got the Bo Selecta box set for xmas (yeah, opened it early). The 1st series disc is not working correctly on my Sony Dvpns700 player. It plays each episode without problem, but when you try to select most of the extra features - the player gives the C:13:00 error message and displays a blank screen. The 2nd series, both discs work fine. I wonder if this is a poorly/faulty manufactured disc or is it branching problems? I've not experienced C:13:00 errors before, so I hoping it's not the player. I noted that on the 1st series disc, it won't display 'time remaining', which I found odd.
