Hi guys,
for documentation purposes I just want to share my experiences for converting media files (e.g. video files) for the Pioneer AVIC-F930BT (bought in Germany).
1. As "Windows Movie Maker" for Windows 7 comes as an easy download I tried this WMV format first. But all custom bitrates and other settings had no success. So I rejected this format.
2. MPEG4 or H.264 as video format for MP4 and M4V with AAC for audio on SD and USB doesn't work well. The sound/video is choppy.
3. I got my best converting-experiences with "ffmpeg" which you can download at http://ffmpeg.zeranoe.com/
