I'm not sure such a blanket statement can be made these days. There
are plenty of apps which grow & shrink buffers on the fly which seem
to be perfectly stable. I suppose sloppy coding and mishandling of
memory would cause the symptoms you're describing though.
On a side-note, a lot of people experience a frozen vdr/xine with 100%
buffer. It's never been fixed to my knowledge and it's been a while
since I've seen it brought up but iirc it has nothing to do with
bandwidth. Rnissl, I think, knows what actually causes that

Translation: path of least resistance. ;)
