The problem doesn't occur with 3.2.10 Guest drivers. All versions above are malfunctioning ! So to try to explain : I'm making videos captures with speech, and for unknown reasons, the videos is not captured correctly : Too fast, too slow or my voices are not correct. When starting the capture, the few first seconds, but the more i'm recording, more crazy will go the capture : Video too fast or too slow, voices not perfect, sometimes the voice can become crazy, or not synchro or whatever... I spent hours to test all kind of versions of VirtualBox until i figured out the VM version 3.2.10 are working smoothly and perfectly whatever the capture. So, i decided to Upgrade to 4.0.2 but to keep the 3.2.10 guest videos drivers, and guess what ? I still can capture perfectly too... There is no error message, excepted after the upgrade, The VM asked me to install the Extensions Pack. But after that is done, it's ok." defect closed guest additions VirtualBox 4.0.2 obsolete Windows Windows
