Hi,

In recent versions of ConTeXt/luatex, I observe the following log entry:

Syntax Error (77727): Unknown filter 'DCTDecode'

This happens if the document includes JPEG images, e.g:

\starttext
\externalfigure[hacker.jpg]
\stoptext



not here, with that image.
Can you give us
context --version
luatex --version
?
