Robert, Thank you for your great review. I too owned the LG BH200 and while there was a lot to love about the player, there were too many huge drawbacks. The biggest being that my unit was plagued by the infamous audio dropout issue. After reading of the numerous users reporting the exact same issue and running through 5 and 6 units before they found a problem free one, I decided to throw in the towel on that deal.
I would love a closer comparison of the SD DVD PQ on the BD55 vs LG BH200 because IMO, after updating the fw, the BH200 has probably one of the best SD DVD pictures of any unit I have seen. That is compared to my XA2 and HTPC with NVidia 8600GT which the BH200 was neck and neck with. If the BD55 can hold its own compared to the BH200, that is a really good sign.
Also, can someone please refer to the manual for the BD55 and clear up if in the speaker setup for the analog outs, it includes: Small/Large setting, speakers level adjustment and distance adjustments. The BD10 and BD50 at least included these so I would think the BD55 is the same. Would be nice if they added an adjustable crossover so it can be set at 80 Hz instead of locked at 100.
