I'm sorry, but the search function seems to be a bit limited (only searches thread titles).

Anyway, I thought that the rotational speed difference would only yield a different frame rate but otherwise compliant PAL signal. I didn't think of the effects on the modulated signal. Since both PAL and NTSC video signals are FM modulated onto a 7,1MHz carrier, playing that back at a wrong speed would shift the carrier frequency, probably causing demodulating to fail. Also, I just noticed the technical discussion forum, where I should have posted this instead. I guess I got too excited about the prospect of playing back PAL discs on the X0. Sorry about that.
