(SOLVED) Message tells me it can't mount DVD. Then mounts it and plays it.

Yesterday I added a DVD ROM (Sony) to my machine (running Gnome 2010) which already had a DVD/CD Writer (LG) installed. It showed up immediately in the BIOS and in the PCC. But I now get a very strange message (strange at least to me) when I go to run a DVD in either device -

"Cannot mount volume.
The volume 'film title' uses the  file system which is not supported by your system."

After which, if I go to start it from - for example - smplayer or VLC - it immediately mounts it then runs it. Also, the DVD's have been run a number of times using the original DVD device - and getting no such message.

The relevant fstab entries are as follows -

/dev/sr0 /media/cdrom ro,user,auto,exec user 0 0
/dev/sr1 /media/cdrom1 ro,user,auto,exec user 0 0

This is hardly a serious problem. But why am I now getting this apparently pointless message? Does it maybe indicate problems to come? And just for the record there is no such message with CD's.

Why have any entries for removable devices in fstab at all?

What happens if you comment out those two entries?

Also note that you don't have to mount a video DVD to watch it, so I don't think smplayer or VLC actually mounts it.

Bald Brick - bit of a messy expression, the way I put it. I didn't mean to imply that either smplayer or vlc actually did the mounting, as I'm sure you're right and they don't.

And Just19 - answer to your first question is - simply because when I checked the settings in the PCC I was given the option of adding it to fstab. Lazily, I said OK. But I should have known because a couple of years ago I had a helluva time time with external hard drives not mounting - until I removed them from fstab. After that there was never any problem.

And so to your second question - if I comment out these two entries, everything plays at its should and I get no funny messages.  Solved. Thank you. I'd still like to know why I was getting a message about the DVD's having a file system not supported by my system - but that's just out of interest now. Thank you again.

Not sure to be honest .... glad it is sorted for you in any case
