Why do 3D films on DVD need a special player?
I'm sure the answer is blindingly obvious, but I have recorded a load of stuff during the Olympics in 3D. When it is played back on a TV you get two pictures side by side until you activate the 3D mode - then it becomes one fuzzy picture - then you put on those glasses!
So why cannot 3D films be made the same way, so that they appear to be two pictures side by side unless you have a 3D TV? Why do you have to buy a 3D DVD player??? |

Although it would be technically possible for film companies to release films in that format, on ordinary Blu-ray discs, to play in ordinary Blu-ray players (not DVD players), that way of producing a 3D picture does not give you full HD resolution, as you've got 2 side by side pictures over the 1920 horizontal resolution.
3D Blu-rays on the other hand do (I presume?) give you Full HD 3D. |

I have recorded 3D programs and also my own 3D footage on to DVD and played it back in 3D on my 3D TV
The 3D Blue ray player has the 3D software built into it I think it should be possible to play back a 3 D Blue ray disk in an ordinary blue ray player and manually turn on the 3D software on the TV |

If you recorded your own 'side by side' 3D BD, then the TV would be able to display it in 3D, just as with Sky 3D. |

A normal BD player won't work. |

Thanks guys, it's resolution then. However I am sure the opening ceremony recorded from BBC HD in 3D looks much better than standard definition and is very near to full HD quality.when I view it. I am going to start a campaign for BluRay 3D films to be released in a side-by-side format because having bought an expensive Panasonic BluRay recorder a year or so ago, I do not want a second DVD player!
