Best shots to save a Match point!

[Saarbrigga]

Hey djarvic,

short off topic question:

You did something in the 1st clip (Ivanisevic) that the clip starts at 5 min 40 seconds.
I see it works when you add #t=5m44s behind the link.

I did try this for an other link (wikiquote), but the clip starts at the time without audio and video.

Can you help me out what could be the reason?
