Incomplete downloads

[Arthur Murray]

Here is what I saw at the end of the download from get_iplayer
(happend twice today on the same file):

So, it was 5% complete the first time, 81.4% complete the second time,
but then it became a "Download Complete" and continued on with the
conversion/tagging process.   Has anyone seen this before?

Is this a problem with rtmpdump (v2.4) or get_iplayer 2.82? Is there
any way to ensure this doesn't happen? Once the file is ffmpeg
converted it can't be resumed manually, so I had to find the file and
force a complete redownload.  It is worrying that incomplete downloads
can be considered complete and I might not notice it before it is too
late.
