Lite-on 5001 Upgrade

Hello Lite-on experts. I have Lite-on 5001. I purchased it about 2-3 years ago and after a few months with VERY little use the drive died. You are all experts on how bad Lite-on service is. The 5001 sat there for almost 18 months until I discovered this forum. With your input, I have replaced the drive with a Lite-on SOHW-1693S, upgraded the FW from the Lite-on site to 1180, I am in process of adding a fan…life is good…except for one thing.

I can read all DVD’s I have made in the past on my PC, all DVD’s made by others, but cannot play simple packaged DVD video. Purchased movies, rented movies, all the same problem, simply will not play. They seem to start up, some even get to the FBI warnings, but then hang. I am in the USA therefore all these videos are region 1. Is this a region issue? Any ideas…

Thanks to all for your help…
