that's correct. This is an (out of standard for resolution) DV stream packed in an AVI file, with PCM audio. You can extract the raw dv stream using something like tcextract -i video_out.dv -x dv > video_out_raw.dv. The latter file will be a _real_ dv stream (tcprobe will confirm it). Most likely, this video stream will contain (severe) video artifacts. You can produce directly raw DV streams using -y dvraw. Bests, -- Francesco Romani // Ikitt
