Background
Feedburner is good to use because it provides you with stats on your RSS feed. In addition to telling you how many subscribers you have, it can also do things like send e-mails when you update your Blog/RSS feed.
Why is a custom URL with feedburn a good idea? What if Feedburner dies in 2 years or decides to take their project in a direction that you don't like? So you move away from them... but there's a problem. All of your subscribers are subscribed to your Feedburner URL... with Feedburner's domain (not yours).
Having a custom URL gives you the flexibility to control your RSS feed as you see fit.
Step-By-Step Guide
Note: This guide assumes you're currently not using Feedburner.
1. Download the Feedburner module from http://drupal.org/project/feedburner/ and enable it.
2. Register and log in at http://feedburner.google.com.
3. Go to http://feedburner.google.com/fb/a/mybrand, follow the instructions, and set up your CNAME. When you can go to http://feeds.yourdomain.com and have it take you to your Feedburner account at Google, you know it's working.
4. Next, burn the Drupal feed you want to use on your Feedburner page at http://feedburner.google.com/fb/a/myfeeds.
5. After you've burned the feed, take note of the end name of your feed. eg. http://feeds2.feedburner.com/MyFeedHere
6. Now to set up the custom URL in Drupal. In Drupal, go to Administer -> Site building -> Feedburner -> Settings and then click on Advanced settings at the bottom. Enter your "MyBrand custom domain" and click "Save configuration."
7. Now we want to burn the feed in Feedburner on your Drupal instance so the redirect works properly. Go to Administer -> Site building -> Feedburner -> Burn feed. Enter the "Local Feed" on your Drupal instance. Next we enter the "FeedBurner Feed." This is the tricky part that many other guides leave out. Remember that feed name we asked you to make note of in step 6? You want to enter that here. If you'd like to test it first, go to http://feeds.yourdomain.com/MyFeedHere (where this is your custom feed URL). It should show you a Feedburner page with some items from your RSS feed. Once done, click "Save."
8. And voila! That's it. If you have any problems, check out Google's MyBrands support page.
Typically, there is up to a day delay with Feedburner updating your feed. If you want to notify Feedburner to update a feed ASAP, enter your URL on their ping page.
