Maybe they have this fixed now.
When I responded (above) to this thread, Tivo support immediately contacted me and said the issue should have (coincidentally) been corrected that same day. Well, for me, it wasn't, but I have been trying it about daily since then but still "failure".
Well, just now I got a report of "Success", so here's hoping it truly is.
For whatever reason, I prefer using zap2it's guide, most of the time.
