I did no such thing. I said:

"I trust," for those who are sufficiently illterate to not comprehend,
is a colloquial phrase that means that I can rely on someone, based on
his proven dependability, to do the expected at some point or other. I
no more assigned anyone anything than any new bug ticket on
svn.mythtv.org does. Jim Westfall will (wait for it), I trust, get to
the fix of whatever issue exists in the FireWire recording code on his
own good time; he does not need you to defend him, and I have no more
ability to "assign" Jim work than I can in helping you to not
embarrass yourself in print.

Never said that. The maximum setting got inherited when I upgraded to
0.20; I never touched this setting during the upgrade because I hadn't
changed it in about eight months.

Well, yes. Again:
* Something in the FireWire code broke in 0.20.
* Jim helped me figure out a way to bypass the issue and will (again,
wait for it), I trust, roll out a fix to whatever broke between 0.19
and 0.20 in due time.
> But your system requires 23.5MB, so 96MB is overly large.
If the setting--remember, it isn't a free-entry field, but essentially
Myth's equivalent to a dropdown box--lets me go up to a certain level,
and there are no warning messages about it, and good reason to believe
that "bigger = better," and it's been working fine for months, and a
software upgrade breaks this behavior, that's the sign of a bug. It is
not the sign that that setting is ipso facto "overly large."

Another non sequitur. You know very well how much (little) a backend
needs for RAM. One more time:
* 0.19 did not have this issue.
* 0.20 does; thus something broke.

My apologies to the entire MythTV developer community for
unintentionally slandering it.

As the Internet has proven a thousand and one times, no license is
needed to prove oneself ignorant and wrong.
