From my job experience with digital electronics I have assumed that the data read in from the disc would go into a buffer memory, and be "clocked out" with precise timing. Parts-per-million would be easy (inexpensive)to do. It would not matter how irregular was the timing of data input from the disc.
I gather that most, if not all, disc players fail to mechanize this approach, and are therefore subject to "jitter" problems. Perhaps this is understandable for a $100 item of equipment, but at high end prices it is inexcusable.
