Check your hardware acceleration drivers (vaapi, vdpau) and try to disable it in VLC preferences.

You can customize the default jump (the one with the arrows) in the preferences.

Shift + Arrow - jump 5 seconds
For cases like yours this is what I use, and usually it gives enough control in the context of a movie.
VLC has very short, short, medium, and long jumps. Go to the preferences to set your own hotkeys to whatever works (I have [ and ] for very short jumps, it's perfect for the use case you describe, when you just want to hear a phrase again).
(Note that apparently you need to restart VLC for the changes to take effect.)
That surprise me, how is VLC complicated?
I use it all the time and it just works.
My only problems:
-For some reason sometimes it hangs in Fedora and I have to kill the process manually.
-I wish that the progress bar allow more control of when to jump. Frequently, in a video, I don't understand what somebody just said but, when I try to go back, I finish jumping back too much.
Apart of that it works wonderfully.
