There's no need to if the playback source can provide lots of data quickly and in advance. However, a network stream source is much more un-reliable, so knowing how much data is ready for playback would be nice. (Even nicer would be to know whether the output device did run out of data.) Currently, my incoming buffers are empty most times, with an unknown amount of playback data in several hidden buffers. As a workaround, my remuxer doesn't get new data until Get() returns Count=0. But there are enough other buffers left... Cheers, Udo
