I'm under the impression that this error is occuring because bad third party
software was installed to the system. Vista is verifying that your software
is not writing to random and bad places in memory. It seems like you have
installed software that is writing to random and bad places in memory - the
DEP check is only pointing this out, as opposed to letting your system
become randomly corrupt.

So:
What codec do the source files in question use? You may not know, but that
would be of value.
Did you install the third party "Vista Codec Pack"? In a very similar case,
that was the culprit, and removing that solved the issue. Or you can
convert the AVI to WMV and then burn it.
Under Windows Media Player's Help:about:Technical Support Information menu
dialog, what data does it give you?

It would be of high value to both of us to identify and remove whatever bad
software was installed here that is crashing. If you could help me with
that by providing further data, that would be great.

Thanks,
-Zach
