Dragon Player doesn't play commercial dvds

Re: Dragon Player doesn't play commercial dvds

Okay. Time to address the hardware. Do you have more than one optical drive in your rig? Do you know what drive type of optical drive(s) it/they are? Is the optical drive internal or external? What type, and how many, interal HDs are in your rig?

HDDs:
A pair of identical WD 120GB IDE drives, both on IDE0
NOTE - Kubuntu is wubi installed on the second drive, Windows on the first (dual boot)

CD/DVD:
1 Samsung SH-S182M CD/DVD writer (multi-format, dual layer, etc.) master drive on IDE1
1 Lite-On XJ-HD163D DVD drive slave on IDE0
both drives are internal

EDIT - Okay, this is odd. I seriously messed up something while trying to fix an unrelated problem and Kubuntu wouldn't boot anymore. Rather than try to fix the issue, I just uninstalled/reinstalled the whole OS (this is just a testing machine) and now DVD playback works... on one drive, but not the other. This is already a 50% improvement over my prior issue, where it wouldn't work on either drive and its enough for me to call this resolved. In case you were wondering, the DVD writer is the drive that still won't play DVDs.

I already had libdvdcss2 installed and I still can't get DragonPlayer to play a DVD. This is what the terminal messages say:

The problem is, there is no /dev entry for the DVD drive and I can't seem to make Dragon realize that. As long as it wants to keep trying access via that route, I don't think it will ever work. It should be noted that on vanilla Ubuntu, the DVD plays fine.

exactly the same erroroutput i had: installing (and automatically starting) the ibus-daemon helped me solving this! i dont really understand why dragon-player needs the daemon, but so it is..

Overview

Guys, this is an old thread, but the problem is still in 10.10, so I though I'd post:

dragon --play-dvd /media/COOL_MOVIE will not work if /dev/dvd is not present as described above.

The quick fix

cd /dev/
sudo ln -s dvd1 dvd # or whatever your real dvd device is

and now launch dragon player.

Analysis

/dev/dvd should exist on most systems, however, there are instances where it will not. For example, if you have no dvd drive, or if you perform hardware changes after install. In my case, I had to replace my old dvd drive with a new one. The new drive showed as /dev/dvd1. The udev system and/or its delegates probably does this to prevent name conflicts if the original drive "comes back."

This really is a bug in dragon player. /dev/dvd is probably ok for a default, but it should honor the mount provided in the command line. And Settings should probably offer an option to set the drive device. Typically, the dvd in kde4.5 is launched from the device notifier (where you pick an action for a dvd), so the correct device should be traceable from the mount point provided on launch (e.g. click on "play movie" probably fires off dragonplayer --play-dvd /path/to/mount, and the actual device is traceable through the system equivalent to df /path/to/mount).

Hope this helps someone!
