[MPlayer-dev-eng] -vm and aspect

[A Mennucc1]

hello

I see two bugs in the -vm implementatio

1)
I have ripped the DVD of Lord Of the rings
(that I own    :-)  )

(I used a script that computes automatically aspect and crop,
and does a 3 stage ripping , see attachment)


if I play it with  mplayer -vm,
though, the aspect is not respected

2) sometimes mplayer crashes after it changes videomode
and says 

....
VDec: using Planar YV12 as output csp (no 0)
Movie-Aspect is undefined - no prescaling applied.
VO: [xv] 240x180 => 240x180 Planar YV12  [vm]
XF86VM: Selected video mode 640x480 for image size 240x180.
X11 error: BadMatch (invalid parameter attributes)

bye

a.
