Do please search this forum under keywords NIGHTSTALKER DVD and within the past 15 days, his advice on the matter (incl. the card swap trick) will be found.

My advice is for you to consider the OrigaChip for US, which will play both DVDR backups (simple swap trick) or import originals (PAL or JAP in your case) no Swap (at least that's the case on my PS2).

If you can't get OtigaChip ( ####://www.origachip.com ) then change your USB mode for a NEO2.2. That'll do the job but won't play import originals.
