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

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
