Hi Mike.  So, do your use compression during your tests?  I guess with newer machines - with lots and lots of RAM - it's not as big a deal as it used to be.  I remember doing great big chunks of vid and having the computer strain to open the thing.  Especially tough after dedicatiing so many resources to Poser.  Poser has never been very efficient with it's use or memory.

I would like to fix the issue.  I'm running Poser 6 and 7 one a Windows 7 Ultimate machine.  I'd be great to hear some suggestions.  I tried (briefly) to find the movie.ocx file online but only came up with a much of comercial or otherwise suspect links.

I do have the legacy Indeo package for Windows XP.  I wonder if just installing some of the older CODEX packs would solve the problem.  I have looked for the file on this, Windows XP machine, and came up empty.  And I stress, I get no such error using this machine - the finished animation opens fine on this machine straight from Poser 6.  It certainly looks like a Win 7 issue.

Taking a computer break today.  Look into this tomorrow or sometime next week.

Best Wishes,
Rance
