yes
A PS2 can play DVDs from the region that it is from
Ireland is in Region 2 for DVDs, so Region 4 DVDs will not play in Ireland.
Most computers play cd's, and I can't think of any that don't.
You can play DVDs for your region
Yes.
Some computers (like mine) dont play dvds or games such as Sims or Zoo Tycoon. They only play CDs.
A North American Blu-ray disc player is generally not compatible with European DVDs due to differing regional coding and formats. North America uses Region 1 for DVDs and Region A for Blu-rays, while Europe typically uses Region 2 for DVDs and Region B for Blu-rays. If the player is not region-free, it will not play DVDs from a different region. However, some multi-region players can handle discs from various regions.
Because DVDs are Region coded and come with other variations in DVD format.
PS3 do not play DVDs from other regions that are not for all regions
No, they are two different regional format. Unless you have an all Region DVD Player which is not available anywhere. Your computer might be able to play these Japanese DVDs but you have to change the regional format of your computer to region 2. Setback is you cannot play Region 1 anymore on your computer.
