DVD Drive Problems

DvChWi · 07-19-2004, 12:44 AM

While trying to play DVD movies and install Unreal Tournement 2004 DVD Edition( in fact, the only two DVD specific things I have tried to do with this drive), I have encountered problems. With DVD playback, Xine give me this error:

Code:

The Source Can't Be Read
Maybe you don't have enough rights for this, or
the source doesn't contain data(e.g., disk not in drive)
(Error reading NAV packet)

This occurs at random times during playback, without any real consistent patterns. DVD playback works fine under Windows using WinDVD, so I know we can make this work in Linux.

The other problem occurs when trying to install UT2k4, as mentined above. This is the only DVD I have been able to test this with, so it may be a unique problem to this disk, but again, it works in Windows. I can mount the DVD and I can browse its file system and see its contents. However, if I try to execute the installer, it doesn't work. If I try to copy the installer, it doesn't work. In fact, I can't seem to actually read any of the files on the disk. When I attempt to do so, I get an error message that always ends with "Input/Output error" as the reason why whatever avtion could not be completed. A dmesg | grep hdc yields something like this most of the time:

Code:

I have no idea what going on here, but I hope I can get it fixed. Like I said, all the operations can be completed in Windows, so I think this is just a matter of tweaking Linux. Some more possibly useful info:
fstab:

Distro: Slackware 9.1

Drive Make: Hitachi
Drive Model: Unknown (how can I find this out without opening up my case and ripping out the drive?)

Thanks for your help!

You can try upgrading the firmware for the DVD drive but this is risky if you do not know what you are doing. I do not know how kernel version 2.6.x sorts out its /proc directory, but in kernel version 2.4.x there is some drive parameters you can set. Have look at "/proc/ide/hdc". hdc may not be there because some distributions sets it as an symbolic link, so look at "/proc/ide/ide1/hdc" if its not there. Also gives us some information that hdparm (use the -I option) shows.

I do not know what is causing the error message below, but I think its the region code not set yet. If you set it in Windows, you do not have to set it.

Download region set tool and set the DVD drive to your desire region. Do a search.

I occasionally get the error below but it did not give me any problems.

With Xine, Mplayer, Ogle, and many others access the dvd drive at /dev/dvd. All you need to do is either set the program to access /dev/hdc or make a symbolic link. If you have devfsd loaded you have to find out the full path.

ln -s /dev/hdc /dev/dvd

DVD players are not very predictable, so you have to close the program and eject the media. Then retract the tray and open the program. You have to repeat these steps multiple times until it plays.

I don't think I ever set the region in Windows, but the DVDs do play fine. I'll double check that. I do have the proper symlinks and paths set-up for Xine. Perhaps I didn't make it clear before, but the DVD does play for some time before telling me it can't seek to a certain block. Thanks for your help so far.

DvChWi · 07-19-2004, 05:27 PM

Update: the region has been properly set in Windows, so I know thats not the problem. I also changed the fs type in my fstab for iso9660 to auto. Still, nothing works right. One thing, these errors:

Code:

buffer I/O error on device hdc, logical block 1594241
attempt to access beyond end of device
hdc: rw=0, want=6376972, limit=961428

I was wondering (and this may sound horribly ignorant) if this drive is somehow being recognized a cd instead of a DVD. That its looking for blocks that can't exist on a CD, but would be there on a DVD. I'm ready to try anything, so ideas are greatly appreciated.

You can try logging as su or root and type
echo "dsc_overlap:0" > /proc/ide/ide1/hdc

This might either make your DVD drive have more problems or it might fix the problems.

Before I try this, two questions:

1. What is this doing?
2. How do I undo it if neccesary?

Electro · 07-20-2004, 12:43 AM

If you use some common sense, dsc_overlap sounds like disc overlap feature does it. I think this feature is used to read the extra information of the CD/DVD near the center of the disc or near the very edge that many CD/DVD disc stop at. This feature might be your problem. It would be the same thing to turn it on but a slight change. As su or root type

echo "dsc_overlap:1" > /proc/ide/ide1/hdc

DvChWi · 07-20-2004, 12:50 AM

Ok, gave this a try but unfortunately it does not seem to change anything.

Shall I just mess around with all those settings, or shall I take another plan of attack?

DvChWi · 07-24-2004, 06:20 PM

Bumping this up. I've done some more reading and fiddling around with various things, but nothing changes. Any suggestions?

linuxnubx · 08-19-2004, 08:00 PM

I have the same problem. My Xine with DVD was working, but now it doesn't... It only works in root now.

Hey, original poster here. I tried out my DVD stuff in root(UT2K4, Xine DVD playback), and it worked brilliantly. So, I guess there is a permissions issue somewhere. Anybody have some ideas?

I did chmod 777 /dev/hdc... And it worked for me.

I did chmod 777 /dev/hdc... And it worked for me.

Tried that, and still no luck. When reading both video and data DVDs, it randomly fails when logged in as user.

Ok, also after doing the chmod 777 /dev/hdc, try unmounting, then mounting, then unmounting again while underSU. Then try mounting with just your regular user. Hmm what else. Check your fstab and see if you /dev/cdrom line has has the option user under it. Mine looks something like this noauto,user,ro.

You can see my fstab above, it has that line in it. I tried that mount/unmount thing, but it didn't help. However, I was able to get UT2K4 installed as root, and I can play it as user, and I guess I can switch to root to watch DVDs(better than rebooting to Windows), though its hardly ideal. The thing that boggles my mind is the way it works for some of it, but not for others. In fact, I got the Unreal installer to work a bit under user, but it would always fail at the exact same file in the installation, every time. Its quite odd.
