A couple questions:
1. Are you using the Blu-Ray upscales, or are you using the DVDs and upscaling them yourself?
2. If you're using the BR's, are you converting it back to 25fps from the slowed-down 23.976 of the BR upscales? How are you handling the audio if you're converting 23.976 back to 25 - using the DVD audio, or speeding up the BR audio?
3. If you're using the DVDs, are you using the PAL discs as a source or the NTSC's?
4. How's that prequel regrade project coming? ;)
