It exists but is it complete? One possibility is that the filesystem
ran out of space at the very end of the multiplexing run.

It will be missing the 'end of stream' info which _may_ cause a
problem with DVD authoring programs - but then again it might work
and the video will be a little short.
If you have the elementary streams (the .m2v and .mp2) files still
around you could try running mplex again after checking that there's
enough space, etc. The other thing you can try, which will be a
little faster and use no extra disc space, is to output to /dev/null
mplex -f 8 -o /dev/null video.m2v audio.mp2
and see if the "Failed write:" still happens.
