need help to 301 redirect, am getting ?q=old/url

I recently migrated from pmwiki to drupal and would like to preserve my old links for seo purposes.

http://www.mysite.com/old/url to http://www.mysite.com/new-url

First I tried this 301 redirect in my .htaccess:

redirect 301 /old/url http://www.mysite.com/new-url

I get this:

http://www.mysite.com/new-url?q=old/url

Then I removed that line and tried adding this one directly below RewriteEngine on

RewriteRule ^old/url$ http://www.mysite.com/new-url [R=301,L]

I've search the drupal forum archives and attempted several other .htaccess rewrites but end up either with server errors or the same ?q=old/url tagged to the end.
