DA5ID  Works great. It solved my problem of a narcoleptic nonsleeping Macbook Pro.

The program is easy to modify. If you want to, for example, exclude EyeTV from the program, or add your own program (like VLC), it's as simple as deleting text, or copy/paste.

HOMER87  I have been having trouble with my MBP not sleeping properly, so the product does the job it was written for. Sometimes when I'm using the MBP I forget to "force quit" in the Activity Monitor and the machine goes to sleep. My only suggestion might be to add "any mouse movement" to the list forcing the MBP to stay awake. I also use Slingbox a lot and unfortunately the machine shuts off if I forget to quit Narcolepsy. I mainly use iTunes when I have Narcolepsy activated, so it works as advertised. I am not really into Applescript or I would do it myself, but I think adding mouse (cursor) movement to the list would be helpful. This is an excellent program if you are having a sleep issue with a Mac., and I assume with future versions the suggestions may be added. Thank you developer.
