My Pioneer player did allow it to be turned off. Then, ONLY a CAV
disc could be paused on a frame. On a CLV disc, you might store a
pure frame, or you might store one of the repeated frames that make up
for the 24 fps film to 30 fps NTSC difference, showing the "jitter
that Bill mentioned.
A CAV disc has 54,000 individually accessible frames. A CLV disc
has ZERO frames which can be accessed by the front panel or remote.
They can only be accessed via time stop. On a film, even a CAV disc
can have those interspersed frames at a stop point. On a picture
disc, each shot is one frame, and is a perfect still. 6 additional
frames get repeated in a film on a 30 fps, NTSC disc.
30 fps times 54,000 equals exactly 30 minutes of video.
