Dieses Skript erleichtert das Betrachten und Aufnehmen mit dem USB Audio- und Videograbber EasyCAP DC60. Vor dem Start des Betrachter- bzw. Aufnahmeprogramms führt es noch einige Tests durch. Das Ergebnis wird im Programmauswahlfenster oben angezeigt.
Damit es funktioniert muss das Paket Zenity und mindestens eines der Betrachterprogramme vlc, mplayer, tvtime oder cheese und mencoder für die Aufnahme installiert sein.
