>I met recently a couple from Argentina; he is an Argentinian and she is a Russian. When I asked her how she has been learning Spanish (they live in a coastal city in Argentina), she said "I watch Spanish/Argentinian movies on VLC Player in slowed-down mode". She said that in this mode there is practically not distortion in the sound quality and all the conversations are clear and slow enough that she can follow it.

Not sure the embedded html5 player (last I heard Flash was dead) within a browser has that option, but a standalone player like VLC should. It can raise the frequencies by the slowdown factor (it's mpeg compressed anyway, so it shouldn't be too hard to tell the sound encoder to multiply each tone's pitch by that number) so you hear the sounds lengthened but not deepened. So install a download helper and get the file from youtoobe (or yoochoob, ie. jućub as we call it here) and then watch it at your favorite speed.

Someone did that and saved it at such - the opening credits song for a local soap opera we had here in late 80s, at factor ten. So it takes 20 minutes to hear a 2 minute song. Alcohol not required, gets you dizzy just trying to listen for the first few minutes.
