"Yes" -- I am positively sure beyond all reasonable doubt that prolonged playback of the DVD sides of DualDiscs in my DVD players, and the CD sides in my CD players won't have any negative impact whatsoever on the lifespan and reliability of my respective players (i.e. compared with a "Redbook" "Compact Disc").But I'll go further than that: If I do play the CD side of my DualDisc in a player (or CD-ROM drive) that has read issues, then I am equally confident that NO lasting physical damage will occur.
Moreover, if any of my players do break, it will most likely be the laser failing -- JUST as is the case with ALL the other 'shiny disc' players I've owned since 1983.
Your Panny was an exception -- i.e. it's motor mechanism failed with ordinary DVDs/CDs because the rotating part itself was substandard. It would have failed whatever you'd put in it. Therefore any statistical correletion you attempt to apply -- presumably based on the variable "rotational inertia" -- regarding DualDisc reliability [in your player] is utterly meaningless and irrelevant.
