Hi All!
I'm trying to merge and convert videos for AirBox tv program. Airbox accepts
mpeg2 videos only that videos are encoded as like;

Video;
Format                           : MPEG Video
Format version                   : Version 2
Bit rate mode                    : Variable
Bit rate                         : 3 410 Kbps
Nominal bit rate                 : 9 000 Kbps
Width                            : 720 pixels
Height                           : 576 pixels
Display aspect ratio             : 4:3
Frame rate                       : 25.000 fps
Standard                         : PAL
Colorimetry                      : 4:2:0
Scan type                        : Progressive
Bits/(Pixel*Frame)               : 0.329
Audio
ID                               : 192 (0xC0)
Format                           : MPEG Audio
Format version                   : Version 1
Format profile                   : Layer 2
Duration                         : 10mn 36s
Bit rate mode                    : Constant
Bit rate                         : 224 Kbps
Channel(s)                       : 2 channels
Sampling rate                    : 48.0 KHz
Resolution                       : 16 bits

so my command line is ;
mencoder -ofps 25 -srate 48000 -vf scale=720:576 -of mpeg 1.flv 2.flv 3.flv
4.flv 5.flv 6.flv 7.flv 8.flv 9.flv avfopts format=mpeg2 -oac lavc -lavcopts
acodec=mp2:abitrate=224 -ovc lavc -lavcopts
vcodec=mpeg2video:vbitrate=6000:vrc_maxrate=9000:vrc_buf_size=1835:aspect=4/3
-o 10.flv

video is encoding with errors like "ERROR: scr 16.872, dts 12.240, pts
12.280" and have synchron problem.
what does this errors mean, and how i can fix synchron problems?
