Does this happen for every copy you've made? Is your specific DVD listed here?

Maybe the firmware upgrade failed :(

Out of curiosity I did a quick Google and found this thread:

At first I thought it's probably not relevant, given it was started in 2009, but skipping to the end revealed the last post was only a few days ago.
Okay, considering the size of the internet that's not exactly a huge number of people having LG Bluray player, DVD playback problems after a firmware upgrade, but it does at least appear you're not completely alone.

It's usually not possible to "downgrade" firmware, but is it possible to upgrade firmware using the same version a second time, just to see if it's some sort of firmware "glitch"?

Knowing the actual model number of your player may help track down some more info, but other than that, maybe calling LG support and doing the very unhappy customer thing (which I guess wouldn't be too hard) might get them to help. Otherwise maybe hang in there for the next firmware upgrade and see what happens.
