[MPlayer-users] Trouble with dvd device name

[Pepe]

Today I tried to play a dvd in windows with this command:

mplayer.exe -dvd-device E: dvd://1

But it failed:

MPlayer CCCP-SVN-r23855-3.4.5 (C) 2000-2007 MPlayer Team

Playing dvd://1.
libdvdread: Could not open E: with libdvdcss.
libdvdread: Can't open E: for reading
Couldn't open DVD device: E:
No stream found to handle url dvd://1
 
 
Exiting... (End of file)

But if I use -dvd-device E:/ instead of -dvd-device E: then it plays.

This dvd was created by my dvd-recorder. I tried then with another disc also 
created by dvd-recorder a few days ago. The strange thing is that this disc 
plays with both E: and E:/. Tried also with a commercial dvd and plays too 
with E: and E:/

So why doesn't the first disc play with E:? What's the difference between 
using E: or E:/?

Tried on linux, and this time the disc plays with -dvd-device /dev/dvd but not 
when using -dvd-device /dev/dvd/

I also realized that when trying to play in Windows a dvd from a folder in 
hard disc (passing the directory where VIDEO_TS is), it works if the path 
doesn't end in "/" but fails if it does. 

mplayer.exe -dvd-device C:/Documents and Settings/Pepe/My Documents/My 
Videos/DVD/ dvd://1

Under linux it works no matter if the path ends with "/" or not.

Playing dvd://1.
There are 2 titles on this DVD.
There are 1 chapters in this DVD title.
There are 1 angles in this DVD title.

I'm developing a mplayer front-end (smplayer) so I really need to know how I 
must pass the dvd device to mplayer (currently I was removing the trailing 
"/" to avoid user's mistakes).
