Hi Giso,

All PQ information must be specified in CD frames. If you do not snap to
CD frames when creating these marks then they will be rounded for you,
which will almost always result in the unexpected.

So maybe the bug is that the CD marker timeline should always snap to CD

Fixing this would result in inconsistent behavior between the various
timeline types.. which might be frustrating for new users.

Maybe you have a better idea of how this should work?
