Very roughly and not accurate for the theory
44.1kHz = 22.67us
if I have average 200ps jitter, some signal output from DAC will come 100ps faster / or 100ps later.
it will distort signal voltage level at each sampling time.
the distortion ratio estimation will be 200ps / 22.67us = about 9.0e-6 = about -100dB.

Not quite: for any steady (DC) level, jitter has no effect.
You can consider jitter to be phase modulation of the recorded signal, and as phase is the time integral of frequency you can apply the analysis that applies to FM modulation to the problem.
Basically it comes down to bessel functions, and can be computed but it is not trivial and a simple conversion to db is not possible.
Matlab and Octave are both useful for visualizing this sort of thing.
