Dust and any thing else that constitutes "dirt" will be the bane of
the Blu-Ray, HD-DVD experience. With pits smaller than bacteria, any
amount of dust on a disc could cause a momentary glitch in playback,
despite error correction mechanisms.

Also, I experienced a momentary video dropout during "Phantom of the
Opera." It lasted only a couple of seconds, corrected itself, and went
on. As I could not repeat it, I suspect a piece of dust was the
culprit. When I took the disc out and examined it, I saw no obvious
flaws, no scratches or fingerprints. Maybe the Toshiba A1's
error-correction mechanism is extra fussy about these things; or maybe
high-definition discs, with the laser having to read smaller data pits
than SD discs, are more susceptible to tiny dust and lint particles.
By extension of this latter logic, Blu-ray, with data pits even
smaller than HD-DVD, might be even more sensitive to dust. We'll have
to wait and see.
