Last question - I assume that you are using the Sony HDWF500 - correct?   I
assume you do the 24p job with the TLS gen set to 23.98, and after your show
is done, set the 3:2 pulldown to 1080i, and dump to Dig Beta for
distribution.  Correct?

I know this seems simple, but it is not spelled out anywhere.

Thanks again -
Bob Zelin
