Note that MediaLab v2010 has now been released and is more stable than v2008 with Windows 7. Some users were experiencing crashes with MediaLab v2008 on Windows 7 but this has been resolved in v2010 and so far it seems to working great. So if you are planning to use MediaLab with DirectRT v2010 on Windows 7, yes, we would recommend also using the 2010 version of MediaLab. For XP, either version of MediaLab ought to be equally stable.
