In the Download view the column headers are non-translatable:
"URL", "Artist & Track Title", "Save To", "Progress"
and also the progress information:
"X of Y K bytes received (Z%)"
By the way: If I change directly from the Podcast to the Download view, its progress bar is missplaced (in my case it's in the right part of the Artist & Track Title" column; MB 2.3.5082).
