Turns out the two features are basically "orthogonal," which is a fancy way of saying that they mostly don't interfere with each other.
Usually, AJAX synchronization involves looking in a specific place for a specific property value. Adaptive Playback usually does not
come into play because such synchronziations are done with structural testing commands based on information recovered by studying the page with the PageMap to find a "fixed point". So none of the commands which could involve Adaptive Playback, like
GotoLinnk or
FollowLink.
But some of these commands, such as
SyncOnSelectedObjProperty, which do require specifying an element ID name and possibly an ID value,
do let Adaptive Playback operate.
The simple rule of thumb is, Adaptive Playback can only apply when the information available in the eValid Script File contains ID tag information -- at least a name and/or a specified value.
You can see the details of this explanation in the
Adaptive DOM Synchronization Explanation page.
