Move/mark files and the associated-part too

There is a folder with many files in it: 112.mkv 123.md5 123.mkv 221.mkv 467.mkv aa1.mkv abc.md5 abc.mkv bbc.mkv dde.md5 dde.mkv ggh.mkv .... xxy.md5 xxy.mkv xxz.mkv How can I move .md5 files and the associated .mkv files to a new directory (using Bash)? 123.md5 123.mkv abc.md5 abc.mkv dde.md5 dde.mkv xxy.md5 xxy.mkv I want to move these files into a new directory, like mkvandmd5/. Alternatively, are there any hints in Midnight Commander to mark these .md5 and associated .mkv files?
