Custom RSS feeds

I have tried to use the custom RSS feeds feature that is near the bottom of the "Web Vidoes" webpage.







I inserted the RSS feed location and get the message that "Your RSS feed has successfully been sent to your DVR," but it is not showing up on my TiVo.



I *can* get the podcast (the Swiss evening news) in iTunes and upload it to TiVo with TiVo Desktop, but would like to automate the process.



Is there a problem with this feature, or am I making a mistake?



Thanks.
