DVD-rom mounting
 

Hello everybody. Hope you could help. I already have redhat 8 installed on my system with 1 cd-rom drive. I added a dvd-rom drive, and it was detected as another cd-rom. It works fine as a cd-rom drive, reading cds. But when I insert a dvd, it doesn't see a thing. when using mplayer to view the /mnt/dvd folder (where it is mounted), no files are seen. Do I need to do any special mounting aside from the autodetection done by redhat? Do i have to recompile my mplayer because I added a DVD drive?

Thanks in advance.

you should create a symlink /dev/dvd pointed to your actaul dvd-rom
I assume DVD-rom is on second IDE channel as slave - /dev/hdd
ln -sf /dev/hdd /dev/dvd
Create a mount point for your DVD-ROM
mkdir /mnt/dvd
next is adjust /etc/fstab so the entry for /dev/dvd looks like this

thanks. it worked great!

already got things to work with Ogle, but the thing right now is dvd playback is too choppy. I am using latest Ogle, and Geforce 2 MX400 with 64 MB. Do I have to do something with Redhat 8 so that playback becomes smoother?

got dma turned on? check the manpage for "hdparm" and search this site. also using a better player could help. http://mplayerhq.hu

ok. thanks a lot. I will try that. I am still finding out how to use mplayer with dvd. mplayer -dvd ??? <--------- what should be next? a vob file? or a number?

a number, corresponding to which "track" is being played. Usually the main sequence is 1, so:
mplayer -vo xv -dvd 1
will usually play the movie just fine.

Cool

yes. I tried it and it works. One more question, I posted outside...

regarding hdparm not able to change my dma status.

Thanks for the quick response.

I believe emulating SCSI on the DVD drive, like alot of CD-RW drive need will fix the choppiness, I forget exactly how to do it, but I believe it was in the grub.conf if you use grub....

Neo77777 thanks for your help it was very useful... now I wonder,
Is the same mounting process required to record cd's?

Thanks to all of you who bother to answer a poor newbie's questions.

well if it says permission denied even as root then add the hdparm -d1 /dev/hdx to a startup file (/etc/rc.d/rc.*) and reboot to resolve the issue...
