I have an emachines 210 with windows XP. As i have both region 1 and 2 DVDs in my collection, i would like to play them both on my pc. However, after a couple of changes, the computer has locked itself into region 1. I don't mind if it has to be locked, but most of my discs are region 2 and it was not made clear that you can only change the region a small number of times. Can anyone help me set the pc to region 2?
