...I suppose I could sort of understand that perception, but I find that
they're frequently essential (or at least extremely convenient) in any
extended discussion, and it seems impolite to not indicate who said what
(if only because then there's the risk of having it be thought that
someone else said it). Still, it's probably not a major issue...

Yes, you're right, I had misunderstood you. In point of fact, from the
few things I remember from the various reports I've seen of problems
with the OpenDML support, I think it likely that the main problem (and
perhaps the only problem) is in MEncoder - specifically in the muxing

I don't remember that, myself... OpenDML support hasn't been a runaway
hit, but except for a few cases where it was being used (in muxing) when
it didn't need to be and problems were arising from that, I don't
remember any reports of problems until the crash thing you referenced.

That and my philosophical differences with you about where the default
"unchanged volume" should be, but that wouldn't interfere with my own
ability to use the plugin.
I seem to remember having tried various different combinations and not
succeeded in getting anything acceptable... but the details escape me,
so I suppose I'll have to try it again when I'm up to concentrating that
much on something non-frivolous.
(I also don't see how the presence of the plugins would help in being
able to test the filters... but that's a side note. 1.0pre6 would
certainly do as a thing to fall back to if I don't like the results of
updating, since it's almost identical to my current CVS tree anyway.)
Warning: Simply because I argue an issue does not mean I agree with any
side of it.
