Possible bug in certain subtitles duration

[BlackHoleSpain]

I have had inconsistent behaviour in some downloaded subtitles.
For example, in this video: http://www.youtube.com/watch?v=q5qjRqXxFFc

No matter the format (SRT, VTT or SBV) chosen, youtube-dl had an error calculating the duration of some of the subtitle lines in that video, where end time = start time.

5
00:00:16,431 --> 00:00:16,431
I will be the only one to see you my sexy lady

9
00:00:26,933 --> 00:00:26,933
Your nice body

10
00:00:28,671 --> 00:00:28,671
Your beautiful legs

The end time is wrong, as those lines (among others) are displayed for several seconds in the real web browser, but the value got by youtube-dl is 0 miliseconds. I don't know the original RAW format, to determine if the problem lies in the program code or the data sent by the servers themselves.

Thanks.

Duplicate of #2457, we just download the files from youtube, we don't process them.
