The header says it all. No apparent difference between CS6 and CC, in this respect. Too bad....
Anyone wishing to test this claim, simply lay down a few minutes of relatively short AVC-I or AVCHD clips on the time-line, then go to the start, hold down the "down" arrow for a few seconds, and note the delay before the recorder window updates and displays the correct frame. Then do the same thing again, perhaps in the opposite direction.
Eventually, the system will become more responsive, as you run through the entire time-line, but that improved responsiveness won't last.
On a side note, that's actually called the Program Monitor in Premiere Pro, not the recorder window.
