I don't know. Maybe a script, which on demand can re-arrange all markers
to snap to CD-frames. My workflow is to place the markers by listening,
i.e., when I found a good place a put a marker, without using the mouse
(or if it existed before, than I replace it in the "Locations" dialog by
"Use PH"). This does not really allow "snap to whatever".

A workaround is to write a script which checks consistency of the TOC
file. That is what I did manually; I will look at it.

Since I am not completely sure that this is really a bug I will not file
a bug report in mantis.
