Some comments:

Using goto for cleanup is a common trick probably known to most 
modern C users. Maybe the C slide should have used goto, or there 
could have been two C slides; the current setup was perhaps 
slightly unfair to C programmers who would never think of writing 
several indentations of rollback-cleanup.

C# programmers might want a word with you about slide #8, as C# 
does have the `using` statement to help with cleanup in a sort-of 
RAII-style way, except it still needs a level of indentation; 
it's not revolutionary and not nearly as good as D style or even 
C++ style cleanup, but it does improve it over the pure Java 
model.

The editor comment would've made a great segue into mentioning 
VisualD - I don't actually know much about the composition of the 
audience, but it is a Microsoft hosted conference :V

I think it's important to emphasize that string mixins are only 
available at compile-time, I think the host of eval()-like 
functions in other languages have soured quite a few people to 
the idea of mixing in strings as code. It should've been obvious 
to anyone who was paying attention, but it's probably worth 
mentioning nevertheless.

Slide #23: font size too big 8)

Anyway, overall, one of the best presentations about D I've seen 
yet, it's always a joy to watch these videos.

Agh, I missed it, sorry! I deleted mine.

(Hey, mine linked directly to the HTML5 version, I take solace in 
this fact :P)

The generalized palindrome doesn't work with odd lengths.
simple fix:

bool palindrome(Range)(Range range) {
     for (; !range.empty; range.popFront(), range.empty || range.popBack())  
{
         if (range.front != range.back)
             return false;
     }
     return true;
}

Call me stupid, but how exactly is the version from Andrei's 
slides broken?

Disregard that, I was looking at the array slicing version.
