Well it has been reported that it works on the Xbox360 HD-DVD player both here ( the PAL version) and the NTSC version from someone i know in the USA so its looking more like the problem is lying with the Toshiba players
That is correct.....I have tested with NTSC 360, PS3, Sony Upconvert, Toshiba Upconvert, & my 3 Toshiba HD-DVD players.
Problem only exists on the 3 HD-DVD players.
