Certainly -- I've uploaded the analysis files for both the -6 and -7 encodes, in case you wanted to compare: http://wootangent.net/~lsd/blah/6.ana http://wootangent.net/~lsd/blah/7.ana The encode seems to proceed normally until 59% of the way through the file, but then it takes a couple of minutes to proceed through to 61% of the way through -- it's during this period that the file inflates up to 9GB in size. The last 39% or so of the encode proceeds normally, too.
