Does your player not recognize commercial disc as well as burned?
We need specifics, player type,media used, burning sw( e.g. VSO,Ner0,Imgburn)…
Also the Xbox 360 will not play mpeg1/2 directly from disc,only supports streaming…If you want to play from disc,then you’ll have to convert DVD to AVI, or mp4 format…
