error on device sr0

[gen_pete]

i just installed a slim dvd RW (liteon) drive and i cannot play back .. well anything

ubuntu recognizes the DVD and mounts just fine, but when it comes to play back all i get in syslog is

..... error on device sr0 .....

with a couple of quick google searches it looks like this is a problem isolated with ubuntu but no one has 100% solved it. anyone else run into this issue?

I am using the test repo's fyi ..


thanks

Can you try to playback the DVD using another video app like VLC?

Is /dev/sr0 the device node for the DVD drive? (look through dmesg to check). I've not heard of this error before anyway.

I tried to use vlc, totem, and mplayer. all failed. I also loaded up live fedora on another thumb drive and it could not play it. these are factory DVD's that i've bought.

the DVD mounted fine to /media/cdrom. and sr0 is the device node.

ill dig up some more logs tonight and reply..

just to make sure the drive and cables worked fine, i attached them to my vista PC and everything worked perfectly. 

some people believe that the issue is related to a BIOS setting (BOIS sees it just fine), or the fact that the drive is RW.

[greyback]

Googling offered the following:
1. Have you installed libdvdcss?
2. Boot with "legacyide" kernel option, could be scsi stack problem.
3. Boot with "libata.dma=1" option. This only enables DMA for harddisks but not for ATAPI devices.
4. Update to latest kernel, as there were SATA changes.
5. Some claim you've to manually set the DVD drive to UDMA2 in the BIOS.

Hope you've some luck

You have ******** installed right?

Open up a terminal and type *********************************

That of course assumes libdvdread4 is at least installed, but if you have VLC on there I believe that'll pull it in.

here's what i get from dmesg

Googling offered the following:
1. Have you installed libdvdcss?
2. Boot with "legacyide" kernel option, could be scsi stack problem.
3. Boot with "libata.dma=1" option. This only enables DMA for harddisks but not for ATAPI devices.
4. Update to latest kernel, as there were SATA changes.
5. Some claim you've to manually set the DVD drive to UDMA2 in the BIOS.

Hope you've some luck

1. cant find it on the system .. best way to install it? its not in the package list
2. didnt work
3. didnt work
4. easiest way to do that ? <dumb question i know, im lazy right now >
5. didnt work

hopefully the log above will help with investigation

have you tried updating the BIOS?  latest version is 1602, I haven't looked through the logs to see if there's any mention of this fix, but they are putting out nearly monthly releases it seems.

i forgot to mention that ... first thing i tried. ... im trying to compile 2.6.29.1 but i am running into some dependency issues. i am hoping that the new kernel will help, but still is a pain in the side.

any other ideas ?

 

[quagga]

As I said in my last post, open up a terminal and run:

********************************

to install ***********.  You won't play Harry Potter without it.  It is not in the Ubuntu repos due to DMCA.  See the Ubuntu restricted formats page in the Ubuntu wiki for more info. 

If that doesn't work, its likely due to an issue with copy protection on that disk (it has some other stuff on it beyond CSS).  But without libdvdcss installed, you're not going anywhere regardless of kernel, bios, etc. 

[gen_pete]

that was it ... dread3 was installed just the above command i guess isn't run by default? Thanks a ton for the help guys ..

[JoeBorn]

I edited out certain parts of this thread.  Believe me, no one feels this is more ridiculous than I do, but, from what I am told, if we even instruct people on how to break encryption we're violating the DMCA.  In other words, we don't have to encourage or help copyright infringement or anything like that, even if we instruct users on how to do something entirely legitimate (like playing back dvds) if that legitimate activity requires breaking encryption its a violation of the DMCA.

It's bad legislation, no doubt, but unfortunately, at this point, it's the law of the land.  I'm really sorry all, I don't agree with it in the least, but I don't feel I had any choice.

[gen_pete]

i totally understand .. thanks for the response.

[acarr]

For what it is worth, here is the Ubuntu community documentation on all restricted formats, which include DVD playback.

Hopefully, linking to this is acceptable, given that it is hosted by the distribution.

If not, then google: ubuntu restricted format

Cheers.
