To everyone burning coasters: I was having problems burning a 5.1/6.1 hybrid for my 2007 Land Cruiser. I followed the directions explicitly, was able to make a functional copy of my 6.1 disc, but no luck on the hybrid. I was reading through a similar thread at toyotanation.com and one of the posters pointed out that he thought there were different loading.kwi files for different toyotas or groups of toyotas and had a link to a 49.8 MB 5.1 loading.kwi file (as opposed to the 45.8MB loading.kwi file regularly referenced here and in other threads for download). Lo and behold, a hybrid disc made with the 49.8MB file worked the first time on my Land cruiser and the override within the service menu was functional. I hadn't read this discussed elsewhere, and certainly don't know where or how to identify the necessary loading.kwi file for each vehicle, but this could definitely be the source of non functional hybrid discs for those trying to make them for vehicles other than the 2007 Tundra which started this thread.

As an interesting side note, I borrowed a 4.1 nav disc from a friend who has a 2005 Land cruiser today (don't know anyone with an 06), as I was starting to wonder if my nav was incompatible with the 5.1 loading.kwi file. The 4.1 disc loaded with no problem into my 2007, and a copy of it was functional as well. The loading.kwi file on the 4.1 disc is also 49.8 MB...
