[MEncoder-users] Unplayable flv movies

Hi All,

I have been trying to convert about 3000 user submitted videos to FLV but  
I am having some problems with mencoder's output format.

An example file is here:
http://67.19.246.210/flv/810567956-1.flv

mencoder command line was:
mencoder -ofps 15 810567956-1.wmv -of lavf -lavfopts format=flv -ovc lavc  
-lavcopts  
vcodec=flv:autoaspect:vbitrate=300:vqmin=2:vqmax=31:vme=5:mbd=1:subq=5:keyint=250  
-af resample=22050:0:0,channels=2 -oac mp3lame -lameopts  
cbr:br=64:aq=2:highpassfreq=-1:lowpassfreq=-1 -o 810567956-1.flv

...and output header is:
MEncoder dev-SVN-r24278-3.4.6 (C) 2000-2007 MPlayer Team
CPU: Intel(R) Celeron(R) CPU 2.40GHz (Family: 15, Model: 2, Stepping: 9)
CPUflags: Type: 15 MMX: 1 MMX2: 1 3DNow: 0 3DNow2: 0 SSE: 1 SSE2: 1
Compiled for x86 CPU with extensions: MMX MMX2 SSE SSE2

I used the standard ./configure.

Can anyone analyse that file, what I am doing wrong, or if you need  
anymore information?
I could also produce smaller files if needed - it is consistent.

As a note, ffmpeg converts this input but produces a garbled output on a  
number of my videos, or cannot convert, whereas outputing to mpeg or such  
through mencoder produces much more reliable conversion (just not in flv  
format which I need).

Cheers,
Ade
