Conversion of rar files to mkv file format

rar to mkv conversion is in most cases not possible, because of incompatibility between the file types. The only "conversion" that would make remotely sense, is if the RAR archive is actually just packaged Matroska movie (.mkv file). In such case you do not need a converter, but a program to extract the .rar files, like WinRAR.
