My LG combo player recorder will not read netflix dvd's

I had the same problem.
1. check that the disk region is the same as you unit ( it is the global of the world on the CD has a number in the middle, now check the back of your player. They must be same region.
2. Turn the unit on
3.Press the power button and hold for 10 Seconds
3. Turn the unit back on, wait for the time to display.
4. unplug the unit and leave unpluged for 30 seconds
5. plug the unit back in and turn it on, the time should not display should be blank.
6. Unit should go into startup wizard like it is being started for the the very first time. follow the prompts.
7. In the setup menue, I believe it is under disc settings, select set to factory settings.

Once I completed these, I put the netflix movie back in and it now runs,

Hope the same works for you
