Oh, hey, no worries. I was able to open the library database in a SqlLite database tool and execute an SQL query to fix them all in one step.
SQL query to do is like this,
update media_items set content_url=replace(content_url, 'OLDPATH', 'NEWPATH') where 1;
replace OLDPATH and NEWPATH with correct paths.

Any chance this could be back ported to older versions? I'm a linux user stuck back on 1.2 but install use it. I would expect the code may work but it won't let me download it.
