Reimar,

that works fine as well. There is still an issue with mencoder bombing 
when picking the webm output format but I haven't researched this 
sufficiently. Might be an error on my behalf or the lack of vorbis audio 
- I have been throwing this binary somewhat together to explore the 
options. It multiplexes just fine into Matroska.

Again, thanks a lot.
