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?
