Oh, I thought perhaps you were rendering to an intermediate file
so you could re-run the encoding step without having to re-render
everything.

Right - that's what I thought was the situation. You're pushing
so hard up against the limits there's no tolerance for the inevitable
peaks that might exceed the limits.

I'd be very surprised if that played in most players. A computer
DVD-ROM drive would handle it but standlone DVD players have such
low profit margins that a cheap "meet the official specs only" 1X
drive is more common than a sturdier/faster (DVD-ROM) drive.

I saw one player with that feature a couple years ago but since
then I have not been able to find that capability in the current
selection of players.

Not while playing the DVD but there is some gooed MPEG analysis
software available for analyzing the .m2v and VOB files (basically if
it's MPEG-1 or -2 it will analyze it). No windows either - in fact
it is not available for windows (which is why I have a copy ;)):

But start at http://www.digigami.com and look around - I'm working
an issue with the author now, but overall it's a valuable tool for
looking at MPEG files
