Multiple feeds and feedburner

[obmob]

Hello! I'm trying to use htaccess to customize my feeds, on one hand there is the global feed on the other one, a podcast forum feed.

I'm using adsense + feedburner, but the common feedburner rule for htaccess transforms any feed into the global content.

Now, this means every little icon in vB4 is useless :p

Anyway, hope someone can help me get through this :)

Here is the original rule:

RewriteEngine on
RewriteCond %{HTTP_USER_AGENT} !FeedBurner
RewriteRule ^external\.php$ http://feeds.feedburner.com/myfeed [R,L]

And I'd love to be able to separate the feed to maintain the podcast category as it is.

RewriteEngine On
RewriteCond %{HTTP_USER_AGENT} !FeedBurner
RewriteRule ^external\.php$ http://feeds.feedburner.com/myfeed [R,L]
RewriteRule ^external\.php?type=RSS2&forumids=3/?$ http://www.mysite.com/external.php?type=RSS2&forumids=3 [R,L]

So far, no luck at all.
thanks in advance :3
