Hi -I wondered if this would play in the USA - I bought two dvds from Amazon UK last year and took them over for my son's family in America when I visited them in December - The Trapdoor series and Willo the Wisp - both designated for Region 0, but he was unable to get them to play on his DVD player/TV set up (They play fine here in South Africa) - I want to order Danger Mouse for them, but am concerned that the same might happen. Has anyone else found an incompatibility with region 0 dvds and the American standard playback equipment?
As far as I know South Africa is a PAL television region. Just look at the DVD version of Toy Story 3 that has a localised SA voice over from Jeremy Mansfield.
Even if you have a region 0 (Region Free) title the TV system must match or the playback and display equipment must be able to handle or convert the other one. In this case the Region code was probably not the cause of the problems you faced.
Most PAL TVs have been able to both display 50Hz PAL and 60Hz NTSC DVDs for many years now or at the very least convert NTSC using PAL60; but it isn't always as easy the other way around for Americans in a 60Hz NTSC country to display our content.
In the USA you really have to check that the equipment can process or display a PAL to NTSC conversion and/or check for 50Hz compatibility of the American Player and the television it is connected to. 50Hz content does not play in America as standard.
it sounds like your American relatives had a problem with the PAL 576 line 50Hz content.
