Just get it direct from Tim... All I'm doing with the emulator is a hacked version of loadguide which grabs the slices from Tim, then gives them a name that the Tivo and emulator can deal with and puts them in the appropriate directory (in fact, I still error check with slicedump by hand, after getting an email from the script that the slice was updated; no big deal since it only happens 1-2x weekly). At the moment I believe the format is AK02113_(today's epoch date)-(today's epoch date +10).slice, so you could theoretically figure it out, but since it's precisely the same thing as Tims in everything but name you might as well just get it there... Also note that today's epoch date will be that of when it was downloaded, and will be California time since the webhost is in the SFBA, ergo it would be 1 day behind localtime here.

The reason for the date ranges is that's how the emulator expires slices; something like 4 days after the last day represented in the slice name it dumps the file. The dates that are on the slices have precisely zero relation to the content, they're just there to make the emulator happy.
