hi i'm not sure if i'm in the right forum but i'll try. i have a dvd/vcr copier [go video] and i was putting my home videos onto a dvd. but i accidently recorded two of the same videos. the disc menu has a place where you can delete off of your dvd [ i've deleted before with no trouble] i was deleting a 5 second space off the disc when it just kept saying deleting but never did.i tried to push stop or anything and nothing worked so i just hit the power off and turned it back on, so now it won't play anything not even an original dvd -nothing at all. it will say reading then spits out the dvd and on the tv it says unknown disc please check the disc. but nothing is wrong with them it won't play anything anymore. the vcr part still works. oh and i tried to clean with dvd laser disc with the brushes[which worked before] but it won't read that either. please help
