I have some dvd media (cheap) that occasionally pixelates or pauses on some scenes when playing in my standalone but is perfect playback in my pc running power dvd 4 xp. Can i backup these backups onto good media i.e ritek g04 (which will hopefully play in my standalone samsung s224 with no glitches)? or is it the player at fault? Time to clean laser?. Hard to say really , but has anyone had similar experiences?
