Fulvio-
Yes, it is that all or none problem that made me leave Pluck on RSS.
I do not do any podcasts, they are, again, forced on you. But, I do get a number of things that are available as podcasts but also as downloads, from my local NPR station. I can go to the site and see what was done in the past few days, and then download an mp3 of just what I want. I have a lot of that.
If you want to see an example, go to wnyc.org, click on Leonard Lopate, or SoundCheck. Also, you can look at "Speaking of Faith" at
http://speakingoffaith.publicradio.org/ also has both podcast and mp3 download. So, I get just what I want.
If I did podcast with lopate or SoundCheck, you know, I would get it ALL.
You can look at the programs that interest you and see if they have mp3 downloads.
I am very happy with MyYahoo! for RSS and with mp3 downloads for "radio"
