Converting Neo HDV to mpeg 2
 

I am a Vegas/NeoHDV user who just got the Bluray authoring application Roxio HDVit Pro HD.

If I render a Cineform master, I can load it into DVDit Pro, but with the following two limitations:

1/ I can't preview it in the final Bluray disc form.
2/ DVDit Pro HD gets the aspect ratio wrong and will render it as a 4:3 frame with pillarboxes on the sides.

Those are the negatives. The positive is that the DVDit Pro HD mpeg2 render is at least four times faster than if I did it in Vegas. I'm sure this is because HDit Pro uses Directshow instead of the slower VFW approach of Vegas.

Anyway, this has me wondering two things:

1/ If Somehow Cineform and Roxio could get together for more compatibility between the two apps?

or alternately:

2/ If there is an inexpensive app that could do a high quality directshow Cineform to mp2 (bluray/HD-DVD compatible) conversion at a similarly quick speed?

Because of Vegas's smart-rendering of Neo-HDV files, my Cineform masters render pretty darned fast. It is the renders into final formats that take forever.
