I have recently studied how to convert video formats from mencoder. Rmvb conversion is required:
1. Copy drv43260.dll to the System32 folder of the system.
2. Start-> Run-> regsvr32 drv43260.dll
(From: http://topic.csdn.net/u/20090515/21/15f70b04-4401-4c0a-99d1-156b09aa01c4.html)
This file can be downloaded from http://www.mplayerhq.hu/mplayer/releases/codecs/, for example:

Because my system is a win7 64-bit system, this error is reported when you run the regsvr32 drv43260.dll command:
The "module" drv43260.dll "may be incompatible with the running Windows version. Check whether the zookeeper is compatible with regsvr32.exe x86 or x64"
I found the following statements online:
64-bit systems generally support 32-bit InstallationProgramRun c: \ windows \ syswow64 \ regsvr32.exe instead of c: \ windows \ system32 \ regsvr32.exe.
So I copied drv43260.dll to the C: \ WINDOWS \ syswow64 folder of the system, then went to this directory and executed the command
Cd c: \ WINDOWS \ syswow64regsvr32 drv43260.dll
Although an error is reported, it is successful. If you try it, you can convert it to rmvb!
