Now I see it. I guess I overlooked it since the title of the thread says "LG GCE-8481B".

Based on that, there isn't as much motivation for going back. You have answered the question as to whether or not the 8520B upgrade caused the problems - apparently it did not.

That sounds good, and confirms DMA is okay.

It is always wise, although something of a pain, to back up firmware before flashing. You might look around here for binaries, or ask on their forum if anyone can supply you with what you need:
However, as I mentioned above, this isn't so critical now. I would suggest trying some other media as your next step.
