I have just captured some screen-shots with GTK-RecordMyDesktop, but now I can't use them. The videos plays right in vlc and totem, but crashs Pitivi and turn into pink splotches in kdenlive. When I convert them using ffmpeg, the video turns into blue and pink splotches. Here is how I'm converting it:
Converting it with vlc crashes the program.
ffmpeg -i out.ogv out2.mpg
I never had problems like this before. I have used recordmydesktop and ffmpeg many times, but on a 32bit computer. I have a 64 pc now, running ubuntu 10.04 x64.
