Ubuntu Won't play DVD's, or else rarely does.

shizz

The reason I say rarely does is that after a few times of opening and closing the tray and various combinations of having it open or closed on bootup /log in, it read the disc once.

The usual scenario is that I close the tray, hear two noises as it sounds like the tray is about to spool up, but then nothing happens.

Any ideas?

I've googled this a few times and nothing has helped. I seem to have all the packages installed etc.

Any help would be greatly appreciated.

Thanks.

1: Technically savvy people watch DVDs? O.o
2: Answer these questions:
a. Is it /only/ DVDs that won't play?
b. What kind of DVDs won't play? Would, say, a data disc play?
b. Could you list your distro, player model, and software you are using (hit Google for the relevant commands)?
c. Are you dual-booting with Windows? Does this problem persist under it?

1. Its Carl Sagan's Cosmos :P
2.
a.I only have one other DVD to check with and it has files on it. These can be read yes.
b. Seems to be commercial DVD's that wont play.
b. Ubuntu 12.04, I'm not sure what you mean by player and software. The OS won't even recognise that there is a disc present.
c. Yes I am dual-booting and no it doesn't persist.

Thanks but I've seen this and applied everything.

I'm really at a loss as to what the problem is.

Have you even looked at dmesg output?

I wouldn't know how to interpret it? Could you?

This is usually the part where you offer hardware information and dmesg output.

Just thought I'd let you know that it randomly decided to read the disc as I turned on my laptop this morning.

Classic it may be, but there must be a reason for it.

What specific disc was it? Does your player read data discs?

It was the same disc that caused the problem in the first place. Yeah it reads and writes to data disc's fine.

Make sure you have the libdvdcss package installed, I think I recalled having a similar issue way back when I usedubuntu even after getting the restricted stuff.

Have you checked the data and power connections to the drive?

Unplug them and reinsert them to make sure you get proper connections.

I didn't realise that ...... but an intermittent problem like you describe is often due to bad electrical contact someplace so it would be worth while checking if possible.

There are often good guides on line for opening specific laptop models.
You might do well to have a look at a couple before you attempt it

Oh I'd definitely do that haha. Its just time constraints more than anything.

Anyways, an update to this is I'm currently testing Elementary OS Luna on a separate partition. It's based on 12.04 but I am not having any of these problems.

DVD loads and is ready to play straight away.
