If you are using .NET 3.5, I would look into the System.ServiceModel.Syndication namespace. It provides a very rich and feed-format agnostic library for handling feeds in .NET. It also provides a lot of extensibility that allows you to plug in additional feed formatters, if needed:

It should simplify your use of RSS, and help you track down odd problems like this, as it provides a cleaner abstraction.

Try using the SyndicationFeed clas. Here is a simple example which will show you clearly how to get this done. If the feed doesn't load then then feed is not constructed properly.
