you uploaded?
No, that's not exactly what I'd experienced or meant. It was more a case
of making sure the input file cut I made for testing/uploading purposes
includes whatever content contributes to the crash - encoding the whole
DVD only crashes at the very end of the last VOB (but too large to upload
all), encoding individual earlier VOBs completes successfully, encoding
only VTS_01_4.VOB crashes at the very end, and as the uploaded cut showed
only the last part of VTS_01_4.VOB is needed to reproduce the crash.
Although I didn't try any smaller cuts myself, if they do encode
successfully with the initial command lines above, the possibility remains
that such cuts then excluded whatever problem content contributed to the
crash.
