I can help later today if you need! I was actually going to replay it so add me on XbL - Brony Swag
I won't be on until later though, because of school and all.
Alright, message me when you try and if it doesn't work I would contact Twinreaper. He is all good and stuff and does stuff that makes stuff work. In other words, he knows stuff that I don't.
One thing with the Remastered version is that some of the walls and whatnot look higher/bigger than normal. I noticed that throughout the game, but when I switched to classic the gap or indent or whatever wasn't there. I feel that it would be harder to jump/trick on something that isn't the normal scale of which you're used to.
I wouldn't say Bungie did anything wrong... They followed what fans wanted. I feel that 343 and Bungie are pretty similar. I hope that I won't be able to see the difference.
