Comment (by Balling):

 "Wouldn't your system ever jitter or drop frame..?"

 Jitter is introduced by mkv container, that has millisecond durations, no
 PTS or DTS. In mkv fork webm they actually introduced some funny way how
 to signal constant frame rate, apparently bug in firefox that it does not
 support that in youtube, lol

 In practice some files on Youtube somehow have this strange issue with
 29970/1000 fps instead of 30/1.001, maybe this bug.
