pixel aspect ratio of PAL DV = 1.0667?

[Michael Mann]

In Vegas the pixel aspect ratio default for PAL DV files is 1.09xx.
The correct value should be 1.0667 instead. How come?

As I understand it, 1.067 is the generic PAR for PAL, while 1.094 (or 1.0926 depending on how it's derived) is the PAR for PAL DV and PAL DVD.
