Running R5A26:

I know you guys get asked to solve DVD issues all the time, so I am trying to figure it out on my own and not waste your time. I see all the assistance you provide, many of which is obviously repetitve, I totally appreciate it. KnoppMyth Rules. Unfortunately, I have hit a dead end and I need at least a nudge in the right direction.

I can play non-commercial dvds from the optical disk interface in Myth. What I can't do is play commercial ones past a certain point. I located the "example" and ran it. I watched for errors and found none during the installation of the script.

Here is some information, I don't know if it will help slueth this:

root@mythtv:/home/mythtv# ls -al /dev/cdrom /dev/dvd /dev/hda
lrwxrwxrwx 1 root root 8 Nov 29 21:14 /dev/cdrom -> /dev/hdc
lrwxrwxrwx 1 root root 8 Nov 29 21:14 /dev/dvd -> /dev/hdc
brw-rw---- 1 root disk 3, 0 May 7 2004 /dev/hda

cdrom:*:24:mythtv,tb12

Adding 996020k swap on /dev/hda2. Priority:-1 extents:1

I would show you the xine log, but I am not sure how. Here is what it says when I type dmesg after trying to play a dvd:

hdc: command error: error=0x50 { LastFailedSense=0x05 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 1472

hdc: command error: error=0x50 { LastFailedSense=0x05 }
ide: failed opcode was: unknown
end_request: I/O error, dev hdc, sector 1492

I can't tell you the exact wording of the error because it is only on the screen for a second.

Again, I am not necessarily asking for a step by step, but any help would be appreciated. (For a linux retahd, I have managed to get working putty, remote X, samba, wireless lan, silver remote, mythtvburn, etc. so I am not a complete waste of your time. Of course, Knoppmyth itself worked pretty much out of the box. Thanks, Cesman.)

Step 1 understand (or at least think about) what you're doing. ;-) Given that the symbolic links and later information from the logs shows your DVD drive on /dev/hdc why didn't you do:
"ls -al /dev/cdrom /dev/dvd /dev/hdc"
The ownership and permissions on your hard disk aren't all that useful. ;-)

The cd_link.sh script is still relevant, as a matter of fact, it's what the install process tries to run for you as part of it's automatic setup. However this most likely isn't your problem.

Your problem is probably just that commercial DVDs are encrypted with something you may have heard of called the CSS. KnoppMyth being a US based distribution, and thus subject to a nasty shortsighted little law called the DMCA, passed by the finest legislator that the big media companies could buy, does not provide support for decoding encrypted DVDs. For the same legal reasons, Cecil has asked that we not discuss the topic beyond that point here.

Have you tried multiple commercial DVDs? Some are better protected than others...

Thanks, guys. Totally appreciate it.

root@mythtv:/home/mythtv# ls -al /dev/cdrom /dev/dvd /dev/hdc
lrwxrwxrwx 1 root root 8 Nov 29 21:14 /dev/cdrom -> /dev/hdc
lrwxrwxrwx 1 root root 8 Nov 29 21:14 /dev/dvd -> /dev/hdc
brw-rw-rw- 1 root cdrom 22, 0 May 7 2004 /dev/hdc

I didn't realize that I was showing the hard drive before. (Like I said, I'm wicked retahded). Now, I see. Duh.

Tried three different commercial disks, no luck. Tried "example" three times -- never an error.

Have you tried running xine from the command line with the disk that's giving you trouble and checking the error messages yet?

No. I didn't. Also found "xine-check". Who knew??

This is xine (X11 gui) - a free video player v0.99.3.
(c) 2000-2004 The xine Team.
X Error of failed request: BadValue (integer parameter out of range for operation)

mythtv@mythtv:~$ xine-check
Please be patient, this script may take a while to run...
[ good ] you're using Linux, doing specific tests
[ good ] looks like you have a /proc filesystem mounted.

[ good ] you have MTRR support and there are some ranges set.

Xlib: extension "XVideo" missing on display "localhost:11.0".
xvinfo: No X-Video Extension on localhost:11.0
[ hint ] Your X server doesn't support YV12 overlays.
That means xine will have to to color space transformation and scaling
in software, which is quite CPU intensive. Maybe upgrading your
X server will help here.
If you have an ATI card, you'll find accelerated X servers on
http://www.linuxvideo.org/gatos/
press <enter> to continue...


Also, I checked both of the above remotely using putty with X11 forwarding. I have read previously that you can't do that to watch video so I'm thinking that probably matters....

..... I guess it matters. Just ran xine-check from XTERM at the penguin and the entire script checked out as "good." I would show you here but I don't know how to do that just yet.

I'll see what I can figure out from http://xinehq.de/...
