dvd
 

have downloaded from frostwire butcan not play it how do i decrypt it.

dvd or video file? Single file (if yes, what is the file extension) or folder with TS folders inside. Description is a bit vague. DVD can mean data disk, video dvd, audio dvd, mp3 disk, picture dvd, etc. :)

i also cant understand this
as LOTR said ripping dvds come as large files in VIDEO_TS folder called BUP and VOB as extensions
videos (usually off here) are .mpg .avi
could you post the extention
only a dvd ripper "DECRYPTS"

what are you using to view?
windows media plays everything
what messages are you getting
"DECRYPT" do mean play? mabee you are missing codecs?
