Up until recently, podcasts of France Inter to which I subscribed would download, but when they reached 100% would not show as "downloaded" but stay as "downloading". This meant that on the next run, they would download again. The podcasts were complete and worked fine so this was benign if wasteful of bandwidth.
Now they appear on the downloads page as "downloading" but never go above 0%. This is consistent with half a dozen podcasts that I tried, including removing the first ones and resubscribing.
Other than that, Juice works great, including on other French radio stations like RFI. So obviously some problem at France Inter. However, I can get all of my podcasts as feeds including France Inter in my Google Reader and they are handled as if completely normal there.
