Wow! That is quite a story. Sounds like you scored enough points for a new PC or at least a new Axim.
Escape plan:
Okay, here is the plan, pick a day (say Saturday), have someone at work ready to call you with an "emergency" early in the morning on Saturday. (or pick something equally urgent to be called away to)
Then ask her Friday night if she would like to watch one of the disks on Saturday morning...
Start watching until you get the call Saturday morning, duck out while she finishes the disk. If you are real lucky the addictive elements of the show will take hold and she will keep watching. If not, she should at least watch an hour or two. You could always call and ask how she is (with real concern) apologize for running out. Ask how the oprah show is? (probe to find out if she is still watching)
If needed and if you are creative enough you might be able to get enough emergencies in to get this over with before the new year.
Also, if you can get 9-10 hours in having watched very little, this will help you implement the "USMC - Retired" plan of asking questions. Since you will have missed enough to be a little clueless.... (However, this can be risky as she may choose to have you watch some of what you have missed already to help you "understand" better
