Screensavers will always prevent your monitor from burn-ins but their will be always moments when you want them to be disabled so they will not disturb you.

Sure, best solution is to be able to disable your screensavers before any activity like ones that I mentioned at beginning of this article and because many other peoples did encountered this problem before us, many softwares have appeared to help us.

The one I found very simple to use because it doesn't have many features but does job very good is Galt Screen Control by Galt Technology. You can download this software from here : http://www.galttech.com/screenshots/screencontrol.html .

It's very simple to use. You just have to right click on it's icon in system tray and select your option.

You will not have to remember to enable your screensavers because you have option to disable them for a selected time, which I found very useful.

If you wish to watch your AVI movie in your PC and this movie was compressed with a particular codec, you will need to have same codec installed on that PC. You will always need one same codec to compress and to decompress not only an AVI movie but any other movie n any other format as well.

There are some codecs which you can use with your AVI movie when you wish that it doesn't loose as much quality as it generally would through compression- decompression process. TSCC is one of codecs which would allow you to compress, transfer and decompress your movie without loosing its quality.
