I already have about a month of buying this model until a week ago and the DVD gave me no problems, the matter is that I gave to a maintenance and now the device does not read this format. apparently there is a code to access this course and not aparace in the user guide. I do not know if you can help me with this little problem, I live in Managua, Nicaragua. and this apparatus purchased in Washington DC. I await your comments. OK!
