Jambe, there was one very, very minor issue with Building Empire that, if applicable, I would suggest you do differently in RtJ. At points where you put "scrolling" subtitles under footage from the DVD, the subtitles suffered from interlacing artefacts, because they were done as field based, rather than frame based to match the DVD footage.

Not a big issue at all, but I'm just thinking of possible complications for those who may want to do an NTSC conversion in the future.
