These files were ripped from the Hong Kong dvd release of the Devilman OVAs.
They are in Japanese with English subtitles. The subs are quite good for a Hong Kong dvd, not the usual gibberish! Until someone takes the time to make a proper fansub of this anime this is the only way to see the first 2 oavs in Japanese with English subs.
The files are encoded in .avi format using the h264 codec with embedded subs.
Hope you enjoy!
