I would also like to propose another solution "global bookmarks" which
means we save only ONE pos file in /home/user/.mplayer/default.pos and
save there only ten "number - pos" and one "q - pos" line where it is
quit position for last played file and bookmarks for the last time
user did save the bookmark. In that way we should also save the file
path we played.
Regards Michal.
