This ^^^ is why I only buy cheap nasty chinese DVD players.
They play anything. NTSC, PAL, SECAM, any region, any file format, divx, mpeg, iso, whatever. Just chuck it in, and it plays.
The obvious downside is they shit themselves in 6 months in an anticlimactic display of communist failure, so there's always going to be a few days between movies while you wait for your brand new replacement $29 player to arrive from Shenyang province.
