Likely the same problems, but at higher resolution, so it might be easier to correct? I don’t know. Don’t have the BR, but I may pick it up at some point and resurrect this project. I’ll update the OP if and when that happens, but don’t hold your breath - if someone else wants to tackle this, by all means, go for it!
I have the Blu Ray but no BD drive, but I did find a 1080p rip from UseNet and had a quick mess-around with tsmuxer to see what it would be like when slowed down to 24fps. I’m just figuring out the best way to slow the DTS audio down.
EDIT - Used Audacity to slow down audio to 24fps and have remuxed new audio and video together. Syncs up perfectly and overall looks pretty good IMO. If anyone wants to take a look at it and give their expert opinion, feel free to PM me.
