It reflects the number of shots remaining before the memory buffer fills. The camera will then pause until the buffer is cleared....
Say you set the camera to CH..You then hold down the shutter release button and start firing off pictures..The camera will fire off 17 shots before the camera will pause, clear the buffer and start over.
Also, just a question..what speed is your CF card?
Just to add to what Knud is saying... the camera will be able to shoot more than 17 frames before it needs to slow down. It starts writing image files from the buffer as soon as you shoot. By the time you fill the buffer, some number of images will already have been saved on the card and removed from the buffer. If you are shooting basic jpgs and writing to a UDMA card, the camera will probably never need to slow down.
