D_J, what about "The Arrival" HD? Is the alternate ending available, too? I was thinking to start a project using LD as source (as probably even that could be better than the retail BD) but if you could obtain an HDTV version of it, oh well, it will be definitely way better than uspcaled LD - of course!
But, LD's soundtracks - and extra features, including the alternate ending - could be a nice addition to the project; let me know if you need audio/video captures and/or some help.
