How to convert mp4 to AVI in Windows

I usually use Windows Movie Maker which is bundled with Microsoft Windows to edit video taken using digital camera. It supports quite a number of video formats like AVI, WMV and so on. However, MP4 is not support in it so far.

To converting MP4 file into AVI file, we may use Quick Media Converter.

According to Quick Media Converter introduction, it enables users to convert between most audio and video formats, including AVI, DVD, Quicktime, Flash, Xvid, DivX, MPEG, MP3, WMA, MP4, 3GP and many others. Users can convert multiple files (of different formats) in a single process and optionally customize the output settings in Expert Mode.

Port 443 occupied by VMWare Workstation 8

In VMWare workstation 8.0.0, vmware-hostd.exe appears to grab port 443. As port 443 is the default port for https SSL, this may prevent other web servers such as IIS or Apache to start on the system.

One solution for this problem is to change its default ports. With the Shared VMs Workstation preferences, we can disable/enable the server, assign a different port for connecting, and change the Shared VMs directory.
