MacOS – Batch repack of mkv files

You could convert the mkv file first with something like Handbrake or iSkysoft's iMedia Converter, then burn it to DVD. Handbrake and iMedia Converter will give you more options for converting than Toast.

You're lucky because the numbers in your file names are in just the order touch -t needs.

This command in the terminal will work. You just need to make sure your working directory is set to the folder you want to do:

for f in *; do
    t=$(echo $f | sed -E 's/([A-z]*-)|([ ,;])|(\..*)//g' | sed -E 's/(.*)(..)/\1.\2/')
    touch -t $t "$f"
done

To break it down:

for f in * sets the variable f to the name of each file in the directory, in turn.

do puts everything until the done into the for loop.

t=$(…) sets the variable t to the output of the commands in the parentheses.

The first sed command matches any letters before a - symbol, the - ; and the space symbols, and the file extension, and deletes them.

The second sed command inserts a period between the mm and ss values, as touch requires.

touch -t $t $f changes the file modification and creation times to the value of t on the file f.

Tested on some dummy files with whatever version of sed ships with Mavericks.
