[vox-tech] mplayer puzzle

[Hai Yi]

Hello, folks:

I've upgrade my ubuntu recently from 7.x to 8.04 and have installed
mplayer. When I tried to watch a movie by typing: mplayer dvd://1,
this came out:

hai at zodiac:~$ mplayer dvd://1

and it's frozen. Nothing works. From my earlier version of ubuntu, it was OK.

I checked this:

hai at zodiac:~$ ls -ltr /dev/dvd
lrwxrwxrwx 1 root root 9 2008-08-20 23:40 /dev/dvd -> /dev/scd0

scd0 should be my first dvd drive (I have 2nd one, which is scd1).


Besides the above problem, I have two more questions if you don't mind:

1. can I create the soft link like this:
ln -s /media/cdrom /dev/dvd

what the difference b/w dvd/scd0 and /media/cdrom ?

2. When I played a movie before (under my ubuntu 7.x) , sometime the
unwanted directorial comments come out, how can I remove it?


Thanks a lot!
