friend of mine has this model of dvd player and it wont play any of his burnt dvds, also it has problems playing some of the latest dvds,weve tried dvd+r or dvd +rw from any brand,all the dvds work fine on other players?cant find any firmware upgrades for this pile of crap.its quite possibly the worst dvd player ive used.worst than my old 30 pound LG player.does any one know of any solutions to this problem apart from dropping it from a great height.
