Ok i know theres always someone on fourms that are new and dont know how to play the Hentai or JAV eps they get so im gonna give what has always worked for me and has never let me down...
First off you will need this codec pack which is wonderful!!!
http://www.cccp-project.net/
Combined Community Codec Pack is what this is called and you can install it with players or without (i usually install just the codecs so without players)...
Also another "codec" you will probably need for anything is DivX which can be found here...
http://www.divx.com/
DivX is used with a majority of movies now a days so make sure you download it and you should be good... (they are starting to have streaming divx movies etc etc so its great to have this codec)
And finally i would recommend VLC player which can be found here...
http://www.videolan.org/vlc/
This player is a clean cut dry player that is really fast without all the fancy stuff... It does have all the controls and if you are playing hentai/JAV or anything that is subbed usually you have to go to "Video" option then to "Subtitle Track" then go to one of the listed options other than "Disable.."
With both of these things you should be able to play any kind of media file out there, of course realplayer/quicktime files will play better on thier own players it is recommended to get them but is not 100% needed since VLC really plays mostly everything... If you are still having trouble playing the file because it wont open or things of that nature you might have to rename the file... Lately i have been getting files like that but its no sweat just a extra step! XD Hope this helps and if you have any questions please feel free to post here and if i cant answer you then im sure someone else can...
