It might be possible to start a recording, check the available streams, 
and abort on a language-set mismatch.

I just had a BBC FOUR recording that started at 18:58 and now plays fine 
in master, but the stream analysis in my cutting script saw 0 video 
streams and aborted.  It worked after dropping the first 45 MB of the 
file.  Needs a probe offset...
