DVSD is one of the standard-FourCCs of miniDV-AVIs (720x480i/720x576i), we used to transfer via FireWire to PCs. The FourCCs could differ because of the transferring program, but storing-format is identical and compatible throughout all decoders for CSDV, DVSD, MSDV. People just rewrote the FourCC of an AVI to choose the best decoder and even rewrote DV-files to Type2-AVI in order to decode & cut it with VirtualDub that times.

So, ffmpeg just has to notice DVSD as a standard miniDV-coding?
