Did you use high quality DVD-R discs like those Verbatim Datalife Plus DVD-R discs (Manufactured by Mitsubushi or Taiyo Yuden)?

Only the 1st release of the SCPH-10000 console came with DVD player v1.00.
It seems odd that your DVD player version is v1.00 though - are you certain that there are no short-circuits caused by bad soldering?
SCPH-10000 S. MINOKAMO v1.01 (Defunct)
SCPH-10000 S. KISARAZU v1.00 (faulty)
SCPH-15000 S. KOHDA (With warranty seal!) :D
DESR-5100 S. EMCS
