Question about DVD Player

I have Pioneer dv-320 DVD Player for half year and yesterday its motor start to noise. Is it normal in DVD players ?
Answer #1
yup..
if its sudden then its faulty. What you’re hearing is a bad hub motor bearing..
Reading starts on the inside of the disc which has to spin
faster to maintain the same information density as at the outer part
of the disc where it can spin more slowly. so whenever u insert dvd it’ll give lil noise..
if its too audible then the motor startin to give poor performance..
Answer #2
Does it happen with all discs?
