All I've done is respond to your posts, let's review:
-> ...the parser.js I found (moviesparser.js) doesn't seem to match this...
<- In the ML version of /Library/Widgets/Movies.wdgt/parser.js...
-> where would I look and how do I find the parser file
<- ...Widgets, like apps, are bundles so just right-click and choose Show Package Contents
-> The only widget folder I see is in the ~user/library folder
<- ...the root of your system drive, where System, Applications, Users, LIBRARY are...
-> ...how to get to the root...
<- ...root Library directory (/Library) http://imgur.com/xxJaXOD...
If you've used Macs since the Apple II, then I would consider being able to find any file given its full path a "must". Everyone should be able to do it on their operating system of choice and it has nothing to do with being a programmer.
If you still want to go ahead, with Finder in front click Go > Go to Folder..., enter /Library/Widgets/Movies.wdgt and open the bundle as described, but i suggest backing up the current widget before you attempt to edit it.
