command: %programfiles%\Media Tools\MPlayer\mplayer.exe
parameters: ?dvd://1 -dvd-device %p
The %p is converted to 'F:\' (mind the trailing backslash) and mplayer really doesn't like that, it expects simply 'F:'.
Also, when trying to play a DVD-video copied onto hard disk and the path contains spaces, there are no quotes around the expanded path when using %P (please don't tell me I need to use %p and DOS features in XP era and year 2006).
Also, I know this is not one of the greatest features in mplayer (and this may be considered a bug on their side), but hell, this is not the only case, there are no standards concerning the problem (and who would follow them if they were
?) and having one more parameter that sends dir paths without the backslash at the end wouldn't hurt.
There are still some programs out there which may look and work in a modern way but their authors have not given them the ability to understand the meaning of spaces in the command line. Some may treat the whole command line as a long filename and others treat the spaces as parameter separators, so these TC options are still very useful.
