Iv just started to download films using MP3ROCKET ,the downloads are going great till I transfer them on to disk which has been DVD+R120 min 4.7gb rw. My problem is that the films are playing on my windows xp media player fine ,no problems but try playing them on anything else like a dvd player or even my sons laptop which is vista acer media player and I have problems like only getting sound or even just not loading at all.Iv heard that you sometimes need to download some kind of codec or somthing to that effect,could someone point me in the write direction ,.maybe a site I could do this from ,or at least some helpfull information .Thanks for reading ,any help at all would be much apreciated.
