My Pioneer DV414 lasted one year before the mechanism failed. My Panasonic RP56 is four months old and already showing signs of the mechanism wearing out. I sometimes play either DVDs or CDs all day long and apparently the mechanisms can't handle that for long. I know many players use the same transports and I see machines from $300 to $3000 using the same transport. Doesn't somebody make a player with both solid mechanics and good DACs and electronics? I have never seen a review mention the robustness of the transport.
