First turn off -wcsaga and -tbp. These are flags that trigger gameplay features that are designed for Wing Commander Saga and The Babylon Project respectively.
Secondly, sort out your mediavps directory. It's a huge mess; reading the installation thread of the 3.6.10 mediaVP's might be a good idea, since it explicitely does tell you that it's a bad idea to mix 3.6.8zeta VP's with 3.6.10 MediaVP's.

Just looking at the file names I can't be sure which of these are old and which are new versions (well, Assets and Advanced are definitely from 3.6.10, as is the Patch file, but right now I don't have the VP versions of the latest 3.6.10 release readily installed so I can't check the checksums). So, I would recommend that you delete these files (or rename it to mediavps-disabled if you desperately want to preserve this mess), download the re-released 3.6.10 MediaVP's plus the 3.6.10 Patch, and make a new MediaVP directory.
Then there's this, which I am not familiar with:
Wokka! Error opening file (JtEP.fc2)!
Error parsing 'JtEP.fc2'
Error code = 5.
This means there is a campaign file called JtEP.fc2 somewhere in your installation, and the game tries to open it and fails, which is the immediate cause of the crash (although you would get serious problems with the mish-mash VP's later on anyway).
I am not familiar with this campaign name; MediaVP's certainly doesn't have it, and I cannot see it in multi-mission-pack either. Considering that there doesn't seem to be any other mods or VP's involved (and seeing you have tried with no mods at all), this is probably some rogue campaign file in your
../FreeSpace2/data/missions/ directory.
The root data directory should preferably be kept clear of all user modifications for cases just like this. Could you do the following:
-go to command line
-navigate to ../FreeSpace2/ directory
-execute
tree /f /a data > data-tree.txt-post this file (data-tree.txt) in
pastebin or as an attachment here. Or even in code tags if you wish.
