Attached patch adds input support for 16:9 DV video in QuickTime.
I found some old files produced by Adobe Premiere and Radius SoftDV which
were affected by this: 4:3 files were marked as type 'dvc ' which already
worked; 16:9 files as 'dvl ' which was missing. PAL uses 'p' in place of
the ' ' spa

positive dts timestamps for these packets, causing downstream problems for
ffmpeg2theora at Wikimedia Commons (near-infinite loop during transcoding).
