I had a problem about that decoder issue too. When i play my dvd that i copied from a vr format, the dvd would play on my regular dvd player but it wouldnt play on my laptop, it says my media player needs a compatible dvd decoder to play the dvd to my media player. I'm wondering if you could help me what to do or what is the compatible dvd decoder for my laptop. I had a Toshiba sattelite series with window vista. I tried to download the codec and so is the decoder from microsoft windows and even my media player but it it says the same thing,i dont have a compatible dvd decoder to play the dvd on my media player.
I would appreciate your help!
Thanks
