No.  If rtmpdump receives garbage, there is nothing it - or you - can do 
about it.  If you're the same Nick as the OP, then you already know the 
solution: use the alternate CDN.

The video files must be edited frame-wise, not byte-wise.  Before 
resuming a download, rtmpdump looks for the last frame boundary as a 
splice point.  You could use an editor to cut the file on an I-frame 
boundary, but I have no idea if that will help.  The "K-S-V" version of 
rtmpdump does a better job of locating the splice point, but it cannot 
resume BBC streams, so there is no help to be had there.

You can try using --start and splicing the pieces together yourself. 
However, "sanity failed" errors usually appear at the beginning of the 
download before much content has been downloaded, so you'll waste less 
time by just deleting the partial download and starting over.  You can 
also supply a single value to --modes and use --attempts=1 to avoid 
unnecessary retries and a bunch of "corrupt file" warnings when rtmpdump 
attempts to resume the download.
