CamStudio v2.0s

The source code for CamStudio v2.0s contains some slight difference from the binary version v2.0. To note, the code for the Record Audio From Speakers feature are absent from this release.

This incomplete release of code is due to the fact that the authors who contributed these portions are still uncomfortable sharing them with the public. We have, therefore, withhold these portions out of respect for these authors.

We are negotiating with the authors and we hope to resolve this issue soon.
