Just a little more background:  I am attempting to put together a prototype of a non-linear video editor using the gstreamer framework.  The .DV file format is a very important format for home / consumer-level video editing.  I'm concerned that if the performance is no good on that format, then it will impede the progress of all non-linear editors trying to use gstreamer.  Does anyone agree / disagree?

Thanks in advance! -Jonathan </blockquote></div>
