Post subject:  No DVD playback on IBM T40 Frontend
So I'm having the same basic problem on a IBM T40 (my front end). I tried the above fix but to no avail
Disk has no encryption... it's sort of like the system just dosn't see the drive as a DVD player (butt it is and works fine under windows). Not sure if this is driver issue or what not, drive read the CD fine to install of course. What information shuold I collect to help trouble shoot this, I really am somewhat clueless about where to start with this one.... several searches have turned up suggestions about updating various things but none of them seem to have hit the problem on the head (tried them any way though :) ).

As the wise one says, you're bit light on details here. Try this:
Code:
grep 'kernel: hd[a-h]:' /var/log/messages
ls -al /dev/cdrom /dev/dvd /dev/hd[a-h]

If the location of your CD/DVD drive as reported in messages isn't the same place the symlinks point to you need to fix the links. If it is, you may need to change the group ownership of that device to "cdrom".

Note! I'm guessing you're asking about R5A??. The answer is different (like - "/dev/scd0") if you're asking about R4V5.

LOL, started a new thread by accident. :oops: man going to be one of those weeks

Yes RA5.10

Ok this was in reference to snapperdragons thread on dvd playback not working http://mysettopbox.tv/phpBB2/viewtopic.php?t=3914

Basic problem is if I put a DVD in and hit play dvd it grinds for a bit but nothing happens. I can't rip either (on the front end)

I did the,

rm /dev/dvd
ln -s /dev/hdb /dev/dvd
chmod +r /dev/hdb

but to no effect and I'm not clear if that is apropreate for the laptop

The first link is right. The second one is not since the extract from /var/log/messages shows your DVD drive on /dev/hdc. To fix it:
Code:
rm /dev/dvd
ln -s /dev/hdc /dev/dvd


Lesson of the day, DO NOT FOLLOW DIRECTIONS BLINDLY! Not even mine. Make sure you know why you're doing something and if it makes sense.

I think the devices need to be owned by the cdrom group for it to work. Try
Code:
chgrp cdrom /dev/cdrom /dev/dvd /dev/hdc

Take another look at the ls output. Links are created with a+rwx pass through so they don't need to be changed, and his /dev/hdc is already owned by the cdrom group. He also doesn't have the "multiple mythtv user and group" problem as shown by the grep output.

I'm testing with a home brew DVD, but I have also tried some of my kids dvd's that show up as not having encytpion (acording to shrink DVD).

I have also updated the dvddcss

The next debugging step is to run mplayer of xine by hand so you can see any messages which go to the console. You might find something in interesting /home/mythtv/.xsession-errors already...

Well I don't see anything telling in the error log... though there is a lot of junk, the myth stuff all seems successful.

I think all that is needed for anon protextected disk is just mplayer /dev/dvd right? Well that is still a no go as well. Guess I'll grb xine or somthign to try to but I was trying not muddy the waters anymore then they are.

So, in the windows world I could remove the driver and device and force a redetect of the hardware? Is there a linux equivalent for doing this?

Post subject:  xine error
So in trying xine I see (xine-check passes everything)

This is xine (X11 gui) - a free video player v0.99.3.
(c) 2000-2004 The xine Team.
libdvdread: Using libdvdcss version 1.2.8 for DVD access
libdvdread: Can't seek to block 256
libdvdnav:DVDOpenFileUDF:UDFFindFile /VIDEO_TS/VIDEO_TS.IFO failed
libdvdread: Can't seek to block 256
libdvdnav:DVDOpenFileUDF:UDFFindFile /VIDEO_TS/VIDEO_TS.BUP failed
libdvdread: Can't open file VIDEO_TS.IFO.

Which makes me think that for whatever reason the system is not mounting or seeing the drive correctly.

I'm having the same problem. When I run mplayer from a command line it works fine commercial or home brew. I think the player activated from inside mythtv butts up against the LIRC Connection refused problem, [which I'm currently trying to debug on R5A12] and this is what causes things to grind to a halt. I've searched the forums and can't find a suitable solution so far... but when I do I'll post it.

Hmm interesting, definitely post what you find. Though in my case I can't get DVD playback at all through anything including xine. It's almost like it it's not mounted or the system dosn't see it or something. I still havn't been able to fix this, so I have just taken to ripping them with my windows box and storing them off on the network share, not a WAF friendlily process though :p.

It's frustrating since there are a lot of advantages to having the T40 as a front end (like when the power rolled today, laptop simple didn't care). I simple lack the Linux-fu to find what the problem is and fix it though I keep trying. I need a big refind hardware stick command and there just dosn't seem to be one :(.
