Comment (by Balling):

 Please add a sample. Also a consensus is that timecode drop and non-drop
 only applies to 29.97 (yeah, drop timecode does not know that it is
 30/1.001 actually and is wrong after a couple of days, see wiki).

 It is a very common problem of Youtube that it uses absolutely wrong
 29970/1000 instead of the correct 30000/1001 too.
