VBR mp3 as well, 1 Meg is far too much for current audio players, most
default to 128k buffer with a prebuffer of 50%.  That's why I made the
default burst in the kh tree 64k.  No doubt video+audio streams should
have more, but you have the added issue of key frame handling.

As long as a reasonable threshold is set, as you still have network lag
considerations for some listeners.
