I was wondering if there are major physical differences between NTSC and PAL discs. Since the signal is encoded onto the disc, the player needn't do any actual signal coding/decoding, just read it off the disc and output it. So my point is that what if it's possible to play back PAL discs on the X0 player. I would imagine at least PAL CAV discs could be played, although with an out of specs signal (625 lines at 60 fields per second). Maybe some highish-end capture cards could cope with such a signal. If not, the signal could be digitized with some general purpose ADC card (maybe even at 16-bit precision!). The signal could then be processed with software (flexibility in implementing the comb filter for example) to be the Ultimate Laserdisc transfer.

PS. the raw digitized signal (sampled at 20 MHz, 16 bits, which is enough for ~2000*625 at 30fps) would be ~270MB uncompressed on a hard drive. Dropping the blank lines would yield ~250GB, and lossless compression might halven that to ~125GB.
