[MPlayer-users] Usage error OR mencoder limitation ?

[hippallium-mplayer at yahoo.com]

Hello everybody,

When I try to encode movies for my iPhone, I sometimes get the following error message with WMV files, and always with FLV (Flash Video) and RMVB (RealMedia Variable Bitrate) files. What does it mean? Is it me not using the right options an is it a limitation of mencoder?

$ file myfile.wmv 

myfile.wmv: Microsoft ASF
