Hello Mark,

As you know the Keylink code reader automatically switches from PAL 
to NTSC but this doesn't solve the sound syncing maths
when two standards (and their variations) interleave. 
What to do when a 24.02 or 23.98 shot film appears in the Pal 
world, or when a 25 film is to be synced to a 29.97 ndf audio track?

A soon-to-be-released remedy will be the Aaton Indaw/Instantsync 
process which adapts itself to all 'drifts and discrepencies' 
encountered on the mixed frame rate borderlines.
We will be showing the INDAW station in operation at ShowBiz LA 
(June 13-15).  In the meantime you can get a sneack preview 
(a light 50K .pdf) on our web site.
