Yes, there is only one brand and model of HDTivo
available the HR10-250, and it will not output
HD and SD at the same time.
i have had SEVERAL customers that are using the HR10-250, and we had the same issues with the SD/HD switching. In one particular system, we have 3 of these units, and they are distributed throughtout the house with a full crestron system. The problem is that some of the smaller tv's in the house (kids beds, kitchen) are sharp aquos LCD's that dont display HD, and they want them to automatically appear when they press a button.
the fix... (heh heh)
I opened each of the tivo's up, took off the face plates (where the format button and indicator lights are) and soldered small wires to the ground, format button, 480i indicator light, and the 1080i indicator light. I then drilled a hole in the back of the tivo, and installed a DIN plug to make it quick-disconnect. I then ran the format button wires to one of the relay outputs on the crestron brain, and the indicator lights to the versiport inputs on the crestron brain. Then i wrote logic in the brain that looks at the versiport inputs that monitor the indicator lights and determines which output mode the tivo is in.
so... when someone uses one of the HD plasmas in the house, the crestron looks at the tivo, and sees if it is in HD or SD... if it is in SD, then it toggles the format button via its internal relay until it senses that the tivo is in HD... then if someone activates a SD tv somewhere in the house, then the crestron kicks the tivo down to SD so that it can be watched by the little tv. When there are no SD tv's on, it kicks the tivo back to the HD mode.
I have done this little modification on over 10 tivos thus far, and it works AWESOME, however... this is not for amateurs or the faint of heart.... you will void the warranty (duh) on your (or your customers) $1000 tivo.
If any of you are in the same boat, and you would like to know the exact procedure on how to do this, feel free to contact me at
