Hi! Not sure if I'll be able to get an answer on time, but I'm trying to make a dvd playable using DVDSP. The movie file I have is apple pro res 422 HQ, and is 2 hours and 35 minutes long. I need to fit this onto a single layer 4.7GB DVD-R. According to DVDSP manual, it seems like if I lower bit rate enough (down to 2.1 mbps!) the video should fit, but I'm concerned because on the DVDSP tool bar display it says estimated file size is 6.7GB. I created the project, set lower bit rate and clicked burn, and it seems to be working (in the encoding process now), but I'm on a tight deadline and can't afford to wait a few hours to find out the file might not fit onto the DVD. Anyone know a sure-shot way of burning a movie at this length and size onto single layer dvd as dvd playable?
