Got it working on the ATV2 with Time Warner. Here's my documentation. Hope it helps somebody else get this running more quickly.

Make sure to also refer to posts #571 & #574 since it isn't clear how the userdata.xml needs to be formatted. I'm not sure if the cookies.lwp file is needed, but I put it out there anyway. In my case, both of these files had to be created from scratch.

This is the part that was unclear to me. You need to replace your default.py file AND edit it to include your SWID and affiliate for your particular cable provider (captured in a previous step). The SWID has to be changed in two places. See post #1255:

Exit XBMC back to ATV2 main page. Restart XBMC. Start ESPN Video Add In. Enjoy!
Many thanks to XBMC debs, Davilla, FireCore, BlueCop, rudawgr, dfa82, Ned Scott, and anyone else I may have forgotten.
