This might help. It's a link to a codec package that is likely to help with a variety of audio and/or video issues that our users occasionally report.
Details
ffdshow tryouts is a free codec update package for use with DirectX, DirectShow, the Windows Media Player (WMP) and other AV technologies. The package can be especially helpful when used with non-Microsoft AV programs such as DirectRT and MediaLab.
Installing this package has been helping some users with video and audio issues in MediaLab--it may also be of help with DirectRT as both programs rely on overlapping audio/video technologies.
Here is the link:

A few important notes:
- This is not OUR software! We're posting the link here because we expect it may be very useful for users having audio and or video issues especially with Windows 7 and later.
- The current release as of this post is v1.2.4422 which was released Apr 9, 2012.
- It may not be initially obvious but there ARE both 32 and 64-bit versions of the package on the download page--see the "Current Official Release" heading (e.g., see attached screenshot of the page when last visited on Nov 14, 2012).
- If you are unsure when installing, try accepting all the default install options--you can always revise choices later and the defaults seem appropriate for most users.
- The package can be uninstalled if desired or re-installed with different options. There is also a graphical user interface you can use to change options after installation.
We'll start posting more info as we gather user feedback, so let us know if you have any luck with it! So far, it seems good.
