For a better functioning of the ClassX applications suggest to make the following settings:
Disable screensaver (Control Panel/Display Properties /Screensaver/None).
Disable indexing files (for all physical disks in My Computer/Right click on the icon of the disk/disable "List disk for fast file searching").
Disable Power Management (Control Panel/Power Options).
If your computer has at least 4GB ram to disable virtual memory (Right click "My Computer/Advanced/ Performance/Settings/Advanced/Virtual Memory/Change/No Page File").
If the operating system is Windows XP set / 3GB switch in c: \ boot.ini:
timeout = 30
default = multi (0) disk (0) rdisk (0) partition (1) \ WINDOWS
multi (0) disk (0) rdisk (0) partition (1) \ WINDOWS = "Microsoft Windows XP Home Edition" / noexecute = optin / fastdetect / 3GB
If the operating system is Windows 7, you must disable Areo Peek.
Install FFDShow 32 and/or 64-bit (install both if you use a 64bit system) for the decoding media files of popular formats. Then disable via "FFDShow Video decoder configuration", the codecs of the following formats: svq1, SVQ3, 8BPS, QTRLE, QTRPZA.
Windows 7 not allows the use of DirectShow filters for decode video files. This means that you can not use FFDShow filters if you want, for example, play the video in DivX/XviD format. To remove this limitation, we recommend the installation of Win7DSFilterTweaker that allows you to change the assignment of the codec.
QuickTime does not support 64-bit architecture. It's not available for 64-Bit systems like Windows 7 64Bit.
Install QTFilter present here for encoding the video in mov format.
