Hi,
Once you have completed your program you will need to publish it. You can publish it anywhere you like on your PC. Opus will create the executable program itself and copy the video files to the same folder. You now need to make a distribution CD (this option to do this appears immediately after you have created the executable program). Opus will create a distribution file (and an autostart if you wish) and compress it all into one file, just burn this file and the autostart to a CD-ROM. On installation the executable program and any video files will be copied to the destination PC.
Have a look
here for a discussion on digital clocks - this will give you some pointers. Also, just type the word "clock" into the search box for more discussions.
Hope this helps
