I can attest to this but not with teh Blu Ray but their standard upconverting player. I own a Samsung D8 (I beleive is the model) upconverting DVD player. Nice menu, really sh?tty remote, nice picture but its starting to skip on some DVDs. Its less than 2 years old and hasn't seen alot of action. My old Electrohome DVD player was built like a sherman tank and lasted me 7 years before finally dying. It was a much better built machine than the Samsung.
When I went looking for a BluRay, I was going to jump on the Samsung (I own a washer and dryer by them and they are freaken nice solid machines) but I shyed away because of the problems I'm seeing with my upconverting player.
I really like the Sony I bought. It feels solid, disk tray slides out really nice, just everything about seems quality. I'll let you know in a years time if I still maintain this impression.
