Support for 16:9 DV in QuickTime

Some files I have from circa year 2000 are 16:9 NTSC DV video
encoded as QuickTime with Radius SoftDV. This marked 4:3 videos
with the box 'dvc ' for NTSC or 'dvcp' for PAL, which are already
supported, but 16:9 videos as 'dvl ' or 'dvlp', which were not.

Adding these to the list for DV codec processing gives the
expected metadata and playback.

I have not tested PAL as I have no sample data, only NTSC.
