LG BD390 Audio Issue and What Player Should I Get Next?

[Mao]

My first player, the LG BD390, has an audio sync issue, especially when playing burned discs. This just isn't acceptable.

I currently use the Panasonic BD65 in my home theater and it suits me just fine (except for the network dongle I had to purchase, which just hangs out of the front of the thing....and the fact that it just doesn't like to play most Universal discs without removing said dongle!).

I'm looking for Blu-Ray player number 3!

I have $200 to burn at Best Buy (or Amazon, though I was at Best Buy the other day) and am looking at:

Sony PS590

LG BP620

Panasonic T320

Panasonic T220

First off, any ideas about fixing the audio issue with my first LG? Secondly, anyone own one of the players above and can weigh in with their thoughts?
