[Vorbis] Direct crash on ov_open

[Christophe Sermet Magdelain]

I had the same problem because my app uses Multithread DLL linkage too.
To resolve it i had to download the sources of the SDK and generate it with
the right linkage settings.

I'll subscribe there and give it a try, thanks...
Just for the record, I'm using Visual Studio.Net 2003.
My app uses Multithreaded DLL linkage to CRT.

Thanks anyways,
