I'm not particularly fond of second-guessing these kinds of things. D-10 is really anal about what constitutes a legal file, so it's probably best not to write anything if something seems amiss. In the end, the real test for correctness is whether the output works with all gear for your particular use case. But segfaults are important to fix, so I'm not too concerned here. Plus my main concern is mxfdec, not mxfenc. /Tomas
