Error using dshwodecwrapper

[Srinivas Sakhamuri]

I have some more information on this, when I remove the registry bin file
then I don't receive the error filesrc0 (see FIRST LOG below) and it starts
playing the mp3 file, I didn't have much success with wma files.

And when the registry is removed it starts to play look at the SECOND LOG.

I am guessing there is some timing issue from the first push and when
decoder is ready causing the erratic behaviour, which probably eliminated
when all the plugins are being iterated for registry creation.

Is there a way we can skip the registry creation, is it only a compile time
option?

Windows builds (http://code.google.com/p/ossbuild/) are probably a bit older
is there a fix in the later releases for any registry related bug?
