[MPlayer-users] DVD aspect ratio confusion

[whyohwhyohwhyoh]

hello,

i'm looking for suggestions about what's causing the following and what
the solution might be.  the problem isn't directly related to mplayer
but i'm hoping that the solution might be or at least the people on this
list might know the answer or where else to look.

i'm transferring some DVDs onto files so that i can stream them to my
PS3.

for most DVDs, just doing...

mencoder -oac copy -ovc copy -of mpeg -mpegopts format=dvd:lsaf ....

works fine.

however, when i try that on my UK PAL "Spirited Away" DVD the result
plays stretched very wide - approx 2.3:1 - on the PS3.

the file plays with the correct aspect ratio in mplayer.

if plays with the stretched aspect ratio in totem (using gstreamer)
which gets the correct aspect ratio if it plays the film straight from
the DVD.

even taking the data from the disc using tccat produces a file which
plays correctly in mplayer but too wide elsewhere.

i don't even know where to look next.  if i switch on verbose output in
mplayer is there something i can look for in amongst all that data that
would give a clue?

tia

PS huge, massive thanks for mplayer and mencoder - richly deserving of
all its awards.  i've been a very happy user for many, many years.  :-D
