Encoded Black Cat into MKV h.264 format with 5.1 Surround Sound English, and 2.0 Stereo Japanese audio, along with English subtitles as well.
I used the Japanese DVD's for the video, and the USA DVD's for the English audio and subtitles.
For playback all you need is the proper codec or media player if you don’t already have it.
Combined Community Codec Pack or the K-Lite Codec pack should give you all you need and more to play these back.
If you do not wish to install a codec pack, a modern Media Player such as MPC-HC or VLC Media Player should come bundled with everything you need.
