Before thinking about binning/selling the player you have, try watching it on your PC just to test it's ok. If it plays fine on your PC, then the player might need updating, check the manufacturers website on how to do that.
Failing that, might need to invest in another player, pioneer do some really good ones, around the £100 mark and they're a reputable make, but as I say, check the files out on your PC first before shelling out any more cashola
