I am talking of the A B repeat function.
In Gom you can do the following
Cick the start position pof your A B repeat - your A position
CLick the B position, your loop repeats
So far the same as VLC...
But then....
If you have overshot the right beginning or end for your loop you can re-click the A or the B and refine your loop to your needs.
If you click the AB repeat button in VLC for a third time, or fourth, you find you simply loose your loop altogether - so you cant refine the loop starting or ending position.
Example, I use VLC for piano tuition, sometimes I want to watch the way my tutors fingers move over a very short piece of video. If I dont catch this right the first take I have to restart again, whereas in GOM I can keep the loop going but refine either the start or finishing position with more precision. Its just better.
If the two little orange buttons on the 'headphone shaped icon' were reclickable then you could emulate this function in VLC.
