Thanks for going through all that. I looked through what you had and I found some things that might be causing the crash. From what you said it crashes when the loading screen pops up right before the menus appear after the movies. If I'm wrong please tell me. I saw someone else with a loading screen crash a while ago that you might want to search this forum for.
Anyway, some of your mods may be the actual problem.
moDems City Life It says in it's description way at the bottom that "There have been reports of this mod, and every previous version of it all the way back to moDem's original mod, causing game crashes."
I advise trying to run oblivion without this to test if this is the cause. If it doesn't fix it turn it back on.
Reneers Guard OverhaulIn it's description also way at the bottom it says, "Though I have tested this mod in several of my own saved games, running this mod could cause your save games to be corrupted, it could crash Oblivion, etc."
Try running Oblivion without it and see what happens.
Supreme MagickaOn one of the versions it says to use Strategy Master's version found here
http://www.tesnexus.com/downloads/file.php?id=12466It also requires the OBSE which you may not have installed. I'm not familiar with it but I haven't heard to many horror stories about it.
OBSE should be found here
http://obse.silverlock.org/I advise trying the game without Supreme Magicka before getting OBSE.
MMM/Mart's Monster ModAre you using the MMMforOOO.esp and MMMforOOO.esm
If you aren't it should be bundled with all the folders that were in the MMM .zip file. Just replace what you are using with the OOO compatible ones.
Mannimarco RevisitedOn its description page it showed a load order example for use with OOO.
"Oblivion.esm
Oscuro's_Oblivion_Overhaul.esm
Other Mods.esp (example)
Oscuro's_Oblivion_Overhaul.esp
MannimarcoRevisited.esp
MannimarcoRevisitedOOO.esp
More Mods.espm (example)"
You might just not have the order in the right place, nothing big.
If you need any help figuring out load order I posted a link earlier that explained it extremely well in my opinion. If that doesn't help, holler and I'll see what I can figure out.
And one last little nitpick.
I think CMbetterwine is bundled into OOO, so you do not need it.
I really hope something here fixes your problem. If all else fails just turn off mods one by one until it works.
I'll try not to jinx you with luck this time.
and Maafiaman, No problem. Glad I could help.
