This is a tantalizing thread, but somewhat frustrating. I can't find Tonto 1.4.8 anywhere (the giantlaser website only has 1.4.4), and what's more, when I look at the properties of the tonto.jar file, there is no checkbox offering a 32-bit option. Can anyone help me? I've been sailing along merrily with my TS2000, but after 11 years, I have a new television and I really want to be able to edit this remote again!

(Mac OSX 10.7 Lion)

EDIT: Found a Tonto.jnlp file which, when run, complains that I don't have the proper version of Java installed. Ran System Profiler to find out what version I do have. Edited the Tonto.jnlp file with TextEditor to update the version number it was looking for. Save and re-run Tonto.jnlp; this time, it downloads a file from giantlaser.com and asks me what name I want to save the app as. Save the file, right-click, and now the 32-bit option is available. Click that box, run the app, and I'm in. Phew!

Now, if only I can find discrete power / input codes for the new TV, I'll be set.
