  issues above might be a cultural thing, but the thing is that i considered all three posts from Rich to be very rude. i tried to answer as polite as i could, given the circumstances.
  if one bothers to take a look at his posts, one could see that Rich stated (on more that one occasion, in several posts) that "bad encoding options" are presumably the cause of the problem, but refused to state which precisely (since i listed all options in the first post).
  i don't get this second pass issue; i thought that stating vpass=1 is sufficient enough for everybody to understand that there is a second pass coming after (otherwise vpass=1 would not be stated at all). i took some time and trouble to write a good introductory post (short, concise, with keywords and configuration), and i thought that would be appriciated. here is an argument to end this issue:

vpass=<1-3>
     Activates internal two (or three) pass mode, only specify if you wish to use two (or three) pass encoding.
       1  first pass (also see turbo)
       2  second pass
       3  Nth pass (second and third passes of three pass encoding)

  there is a very good reason, but it will probably be misunderstood. i work on a highly conservative platform where only a couple of installations (not that mplayer needs to be installed) are allowed during the year. target number is zero changes per year. so, i only change something if something must be changed to provide new required functionality (which is not the case here).

  at last, i would like to thank everyone once again for the help provided.
