Every now and then the DVD drive starts up this awful buzzing sound whilst playing a DVD.  It is VERY annoying.

The “fix”, whilst in mid-movie is to prop the media center on a strange angle, changing the balance and stopping the buzz.

After a while this doesn’t work, and makes the media center look a bit sick.

Anyway, I was talking to a computer technician and he said the that round things that hold the dvd in sometimes get muck on them, which causes the dvd platter to spin unbalanced and thus make the sound.

So cleaning this (a great deal) fixes the problem.

I haven’t ever noticed this on any other dvd drive, so I think it’s a particular weakness of whatever the drive is that came with this HP Pavillion.
