For what its worth, for the past year we have been exporting :30 spots in QT uncompressed to DVD, importing them into an Avid Symphony at a local studio where they export to a DigiBeta master. Station dubs are (for the most part) still in Beta SP and these dubs are made from the DigiBeta master. In my experience, anything going out for network requires DigiBeta.
Last year we did a series of auto races for national broadcast which we mastered to Beta SP ourselves, then dubbed to DigiBeta for delivery to the network.
I agree with the above that the price of a soon-to-be-obselete deck will pay for a LOT of DigiBeta dubs. HD is another matter- we will probably have to pony up for an HD deck…once we decide on which format to standardize on internelly.
