Will a store bought Region 2 DVD work on my US DVD player, I've had ripped DVDs work on it but will a store bought?
Unless your US DVD player is a multi-region player, NO. Typically a US player is Region 1 only and NTSC video format capable. Region 2 disks are typically in PAL format. You will need a multi-region, multi-format capable player or you will need to convert the disk (Region and video format).
