cd-rom jitter

[Arcady Genkin <a.genkin@utoronto.ca>]

When using cdparanoia, it *always* shows ":-|", which stands for
"Considerable jitter", and often ":-/". I've been wondering, while
having a Plextor CD-ROM, am I getting worth of what I have
payed. Anyone extracting with mostly ":-)"?

Can anyone define `jitter' as applicable to a CD-ROM? (or direct me to
a resource where it's explained)

I'm thinking of contacting Plextor tech. support about it, so I want
to reas something on the topic before I do that.
