[Help]About (de)mux aac or ogg into(from) rm

[leiming2006]

I have downloaded dtdrive and replaced rmfformat.dll, smplfsys.dll and rmwrtr.dll with which were from RealProducer 11.
But it was still unable to recognize the ogg or aac file.

It returned:

F:\temp22\DTDriver>dtdrive 12.ogg -W 11.rm
*******************************************************************************

F:\temp22\DTDriver>dtdrive 12.aac -W 11.rm

But in other threads I saw others do this successfully.
Have I got a lack of some DLLs? Or was this commandline wrong?
