Further info on the non reading dvd writer

I have had to put this thread here because i own MSI dvd burner and it does not have a group of its own,quick catch up is this,when i burn a dvd iso using nero and this msi burner it will not read its own burn,it says there is nothing
there,if i burn cds or dvd files it reads them perfectly and the dvds play in a standalone player,it seems its isos only it cannot read,i have updated to the latest firmware but still no success,the burnt iso disc can be read in another msi burner but not the one its burnt from,now the funny part,i took the disc to a friends,his dvd rom could read the disc but could not copy anything from it,the pc just locked up when he tried,could anybody give me a clue whats wrong. :bow: :confused:
