Right now, I'm trying something even more insane - I'm ripping the disc onto my DVD recorder (which has a built-in hard drive) and I'm going to split it up so I can burn it onto my own single-layer discs. That could actually work (though whether image quality of the end result will be worth it, I can't say).
Yeah, it's definitely time-compressed. I can't believe we never even considered that it would be - most movie airings are these days.
I still want to get a usable rip if I can, just so you can see it and decide for yourself whether it's not worth it.
