301 Redirects working for hidden index.php but not for <file>.php

I am moving a client from a custom developed PHP site to WordPress. I am now in the process of using 301 Redirects in the .htaccess file to move the old locations to the new ones in WordPress. Some of them are working and some not (meaning it serves up the “old” location). I have the standard “pretty permalinks” mod_rewrite section in the file and then all the 301’s.

So, the ones that have an original location that are listed like a directory (re-written index.php) work and the ones that have an explicitly named php file do not. Examples:

This works:

Redirect 301 /about/ http://deanchiropractic.com/about-us/

This does (still serves dr-jon.php):

Redirect 301 /about/dr-jon.php http://deanchiropractic.com/about-us/dr-jon-dean/

I have tried changing the order around, tried having the 301s before and after the mod-rewrite section, tried with and without a DirectoryIndex line. I’ve also verified that i am editing the .htaccess in the webserver root.

I’d rather get my .htaccess working than put php to do the 301 Redirects in all the files that aren’t redirecting (I have tried, and verified that using one file).

Here is the entire thing for reference:

I’ve searched wide, and on this site and can’t find a match for my exact problem…though I’ve learned a lot about .htaccess in the process (still a n00b tho). Thanks….
