Splash Lite is an excellent player with a great user interface however unfortunately it cannot play DVDs. VLC Player, plays about everything (except blu ray discs). Klite Codec Pack fixes many of the codecs within Windows and to allow windows media player for example to play more files. WinDVD is a feature rich program for playback of HD DVD formats. AnyDVD HD removes copy protection and also DVD regions.
GIMP is an excellent piece of software for picture editting, including fine rotation (angle controlled) and brightness and contrast settings. Inkscape is a vector based drawing software, it is open source but I personally prefer Microsoft Office Visio 2010. PageDefrag
