yes they do, with a special modification.
Stock Wii's can not play DVD's.
No.
No, although Wiis can be modified to play DVDs.
1.no i don't think so unless the advanced wii's
yes they can play both
Yes Play Station 2 can play DVDs.
Yes it was designed to be able to play DVDs
A PS2 can play DVDs from the region that it is from
Probably not, (Ahem) There are 2 regions of Wiis. PAL and NTSC. PAL Wiis can only play PAL games. NTSC games can only be played by NTSC Wiis. NTSC is usually for The USA, PAL is generally for everywhere else. There are also NTSC-J Wiis in japan.
All Nintendo Wiis in Europe are classed under the same region "PAL" this means that any PAL European Wiis will work in England.
No the Playstation does not play DVDs, only the PS2 and PS3 can play DVDs
All DVDs can play on Blu-Ray players
Yes all PS2s can play DVDs so can the PS3, but they can not play all DVDs from any area or format. No DVD Player can do that. Playstation can not play a DVD because it has only a CD and is not DVD capable any more than a CD player can Play DVDs some playstation2 can play DVDs and some can not .it depends on the area
you cant, you only need one wii console.
