The DMP-BD30 has a kit available that when modded, will allow you to play disks from all regions...but its $1000 usd and you have to void its warranty.....
A cheap+popular dvd player is the Cyberhome CH-DVD300.
Its like $20-40, is multivoltage, multisystem, region-free and has output for component...but its not hd....480p...maybe 720p at best....
