DV-2-XviD 0.8 support auto-detecting aspect radio of DV AVI stream!

Although OpenDML has defined "vprp" header to save aspect radio information. But in DV AVI file, it doesn't store vprp info. Fortunately DV has itself AR definition format.

When I began coding DV-2-XviD and tried to get datetime from DV avi, this great article was a important reference. Now I found it also describes AR-definition bit . But it doesn't point howto analyse it.

Then I found a detail algorithm in libavformat/dv.c (a part of ffmpeg) and merged it into DV-2-XviD. It works well. :)
