Sorry this is so late as a response (I've been away) but the fix is easy Sam; you can exclude the ninth track like this....

./ffmpeg -i input.mxf -map 0 -map -0:9:0 -c copy -c:v prores -profile:v 3 output.mov

The "-map 0 -map -0:9:0" will tell ffmpeg to copy all streams EXCEPT stream 0:9 - which in my case is a metadata track (possibly TC - not sure).

HTH someone...

Definitely another useful piece of information, thanks.
Unfortunately I *do* need the ninth track (TC) so the tracks must be specified explicitly.
