i just attended a training session by Chris Meyers and his advice for this kind of thing was ASK the folks who will be doing the conversion. There are hundreds of options and if you just guess you’ll be going back and redoing the project. Many times, the best results are had by just handing a hq tape to a transfer house and letting them upconvert, that is, if your project is already done in SD… I’d trust Chris, from what I gather, they do this stuff every day.
