[MPlayer-dev-eng] config string

I am trying to decode two 4CIF streams by mplayer remotely via RTSP (live
555) ,
they are both 704x480 at the source but they get decoded differently
by mplayer.
First one plays fine while the second one shows split screen. Note the
aspect
ratio decoded improperly for the second one. Also note the difference in
size of
VOB header - first one is 5 bytes and second one is 6 bytes. What exactly
would
cause mplayer to decode differently so I can focus on that area only?

The two config strings are:

00 00 01 b0 ==>f5 <==== VOS header
00 00 01 b5 ==>09 00 00 01 00  <===== VOB heaeder
00 00 01 20 ==>00 c8 88 9d 4c 61 f4 c5 81 0f 05 06 0f  <===== VOL header


[ffmpeg] aspect_ratio: 1.466667
VDec: vo config request - 704 x 480 (preferred colorspace: Planar YV12)
Trying filter chain: vo
VDec: using Planar YV12 as output csp (no 0)
Movie-Aspect is 1.47:1 - prescaling to correct movie aspect.
VO Config (704x480->704x480,flags=0,'MPlayer',0x32315659)
VO: [directx] 704x480 => 704x480 Planar YV12

and


00 00 01 b0 ==>f5
00 00 01 b5 ==>0d 0f 00 00 01 00
00 00 01 20 ==>00 d0 9d c0 00 4e a6 40 03 f0 00 9c
