I doubt the previous implementations of "start" and > "end" gave you a 3 sample accurate resolution even for wav files. I'll chime in here, having done extensive work with audio and video codecs. With current codec implementations getting sample- or frame-accurate resolution is largely a pipe dream. (Outside of the realm of platforms dedicated to content production and playback.) Especially for video there can be several seconds between keyframes, frame-accurate jumps requiring complex buffering tricks. A reasonable forward-compatible solution would be to allow (by whichever method settled upon) millisecond-resolution to be specified for setting/resetting from where/to play the clip. User agents could implement a best-effort, not needing to guarantee any specific resolution at this point. Regards, Max Romantschuk -- Max Romantschuk max at romantschuk.fi http://max.romantschuk.fi/
