[MEncoder-users] Mencoder killed when using vfw

[Yoann Maheo]

Hi,

Ok, I find the solution.

Mencoder was unable to load correctly the DLL.
I saw that when I try to load Wine :

/Warning: memory above 0x80000000 doesn't seem to be accessible.
//Wine requires a 3G/1G user/kernel memory split to work properly.
//Killed/

The solution to solve this problem is here :
