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 particular problem. > In the end you set them as big as necessary, and as small as possible. > And giving them a fixed size (possibly configurable) is less > complicated, especially in a multi-threaded environment. Translation: path of least resistance. ;) Cheers _______________________________________________ vdr mailing list vdr@linuxtv.org http://www.linuxtv.org/cgi-bin/mailman/listinfo/vdr
