When a CD player is playing a disc without any sort of anti-skip protection,
it spins the disc at 1x, and attempts to correct whatever errors it gets.
If it can't correct them, it does the best it can and keeps going.
When an anti-skip feature (such as Sony's "ESP") is in use, the disc is
played at a faster speed (perhaps 2x), and when uncorrectable errors are
encountered, the failed section is re-read. Because it's reading faster
than it's playing, the player occasionally has to stop reading and wait for
the player to catch up. Because the disc is still spinning, this requires
seeking back along the spiral track to the point where the player left off.
A common symptom of media incompatibility is trouble seeking between tracks,
so the need for frequent seeking magnifies any problems that the player
is having with the disc.
The skip protection feature can usually be turned off on portables. On
car players you may have to find a brand of media that works better.
