Wisten jullie dat je met mencoder tv-programma's kunt opnemen als je een TV-kaart hebt.
Ik niet dus, maar een dagje surfen en rommelen heeft een mooi scriptje opgeleverd, dat samen met het "at" commando een geweldige mogelijkheid biedt om van je PC een "werkende" recorder te maken.
De reguliere programma's kreeg ik niet aan de praat.
Nu nog een grafisch schilletje..
