I found a cool video software that can do a lot of conversion
of videos into different formats and even adjust the size,
the quality, etc etc.
This software can mess around with all of your existing DVDs,
VCDs, existing videos, make them smaller, more compact,
change the format (eg. from mp4 to avi or vice versa) and
so on and so forth.
I found a little video on YouTube to guide anyone who wants
to download/use this software.
