The LG GP57EB40 DVD writer is capable of playing DVDs. It is a Super-Multi DVD Rewriter, which means it can read and write various DVD formats, including DVD±R, DVD±RW, DVD-RAM, and more.

Regarding multi-region support, the LG GP57EB40 does not explicitly state that it is multi-region capable. Typically, DVD players and writers are region-locked, meaning they can only play DVDs from the region they are designated for. If multi-region support is crucial, you would need to check specific regional settings or modifications, but it is not a standard feature of this device.
