IDEA: Download only new Podcasts from website

[wetsmellydog]

There are several podcasts that I listen to. I go to their website or archive page to get the latest offerings.
On the pages are several links to the podcasts available. I would like a program that will compare the files that I have
in a folder with the ones on the website and download only the ones that I have not downloaded.

I have tried numerous add on programs to Firefox but have not had any luck in being able to single out only the newest files.

An example of a podcast page I go to regularly is Buzz-Out-Loud tech podcast found at http://www.cnet.com/8300-11455_1-10.html

They do daily shows so there is a new podcast every day.

Thanks as always!

Juice is one of the best podcasts receivers (if not the best). I don't use it, but it probably does what you want ... and a lot more 

Oh, by the way, it's donationware
