My project has kind os stalled at present - work / life has been rather busy, and the last time I looked I was having issues with sync on TPM, which has blunted my enthusiasm. Hopefully I will get a chance to take a look at things on Sunday.
Still probably going with Cinevision as it's what I know - just don't have the time to play about with x264.
I'm sorry to hear that this project has stalled but I do hope that you're able to overcome the issues that you've encountered and get back on track soon as it's been looking very promising.
Incidentally, were you aware that Wookie Groomer has requested assistance in obtaining the Sky caps of TPM and AOTC over on his blu-ray thread? I asume that you have these to facilitate your project so thought you might be able to help Wookie Groomer out?
