My DV-980H has been going like a champ since 2008. For a hundred and something bucks, that's not bad. Am constantly surprised by how well the externals casing and the design style have held up - looks classier than most current day plasticy, jetsons-ish disc spinners.
Now that I moved the DV-980H to duties in my home office as an audio-only transport, I can hear a low but clearly audible sound from what seems to be the disc unit spinning irregularly. Am in dialogue with Oppo about it. Hopefully they'll come though with a solution.
