I tried doing a code search using TiVo remote but no luck. I just got the Harmony 670 remote and it works like a champ for the Hannspree (Hanns-G) Xv37 model and tivo. Only catch about the Hannspree (Hanns-G) Xv37 is that the TV/Video Input works in an unusual way if you have notices. When you click on it, it doesnt toggle thru all the choices, instead it pops up a screen for you to select. I Wish Hannspree (Hanns-G) people do some about it in their future models.
