(My answer wasn't wrong but your command line does not make
much sense.)

If your command succeeds (ie you ignore Hans' warning but still
get a useful output file) the following will also work and has
many advantages (apart from not showing a muxer warning):
cat CYD-001.vob CYD-002.vob ... >CYD_copy.vob
