Crazy bugs while capturing Videos + Sounds

[Aurélien]

Hi,

Whatever the tools i'm using for Capturing like Fast Stone Capture for Videos + Sounds in WMV format or Camtasia Studio 7 with Audios + Videos, i'm having a lots of issues with Video Guest Drivers that i figured out finally after some days of fighting this.

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.
