AVCHD and opensource tools

Hi,

recently I tried to convert a AVCHD video from Panasonic camcorder. I tried many different tools but most of them fail in transcoding the video in different ways.

Avidemux opens the video, but seeking doesn't work. If you convert the video, it duplicates frames and the final output is slowed down twice (I didn't use any deinterlace filters).

The same happens with FFmpegSource AviSynth filter.

DgAVCDec causes some blocking artifacts.

CLI ffmpeg transcoder produces 2x faster video then original.

Do you know any simple and working process to convert AVCHD video to SD AVI/MPEG-4?

It seems that FFmpeg can't handle the 50i H.264 correctly for some reason. And since most opensource tools are based on FFmpeg, they have the same bug.
