Hi, Broni,
After reading your last post, I understand why you said that you do not have problem playing home--made video discs.
For one thing, you are using almost high end stuffs, the next thing is the way we make the dvd discs.
You duplicate disc by burning from disc to disc whereas I make a video disc by copying from VHS tape by means of a DVD recorder. Mind you, I do not have problems with the movies disc purchased or rented from outside.
I wonder if you could copy a VHS tape or record something from TV onto a DVD disc and then play it with VLC and see if the disc will be open right away once it is inserted into the drive. It the result is positive, then I really have a problem somewhere along the line.
