HME App to Start Recording on Another TiVo

Hello All,

I have looked but have not seen an HME app to tell a networked TiVo (same house) to record something. I have a SlingBox Pro hooked up to a Lifetime Premiere that is only setup for OTA. I would use this app (if it exists) to tell another TiVo hooked up to cable to start recording a live program so I could then remote view it via the SlingBox. This would be similar to hooking up to a Mini (which I don't have)

Has anyone seen such an app or have an idea of how to do this? I use the Sling Player on my phone so using a PC program to do this would not work.

Thanks...Brad
