Hello, GShep -- recording the audio for each slide and
importing the file is a bit tedious but makes a perfectly sync-ed
presentation. There is no reason why it needs to be "choppy." I
record the whole thing, then cut it up with a sound editor.
Assuming transitions are accurate the result should be virtually
seamless. Some of us have a really hard time doing two things at
once (reading a script and mousing / clicking), so this lets you
focus on one thing at a time.
