Page 1 of Portable DVD/MP3

Am looking for a region-disabled/hackable portable DVD player with MP3 on CD-R capability and digital sound out. The only machine I`ve heard of of this type is a Shinko, but cannot find importer/retailer contact phone or e-mail address anywhere. Can anyone help?

Alternatively, does anyone know of any other machines of this type (other manufacturers) and have details?

If there is nothing on this front, does anyone have anything to say about the few portable audio-CD/MP3 "discman"-type machines just out on the market?
