Throwing away samples and repeating others periodically is not what I call "reclocking". In my opinion is just garbage. Is making the jitter permanent (embedded) in the data.

You "de-jitter" only clock. But the data has the same jitter. Jitter comes from the mechanical process of reading of the optical disc, not from the clock itself.

Replacing the jittery but syncron clock with another one "clean" but with different instantaneous frequency from the data (even if long-term would be the same frequency), would make data samples to be skipped or repeated periodically.
