LG DR1F9H Super Multi DVD Recorder Problem.

Question

I have the above recorder with a problem that has developed recently. When a dvd disc is inserted to play, the recorder immediately goes to pause. By overiding the pause function by holding down the play button it will play the disc normally. Once in a while it will play the disc normally without going to pause!

Everything else is OK! Wondering if anyone has encountered this problem and have a solution.
Thanks,
Gary
