Can't find this and TiVo support won't verify this for me. Best buy is having a sale on the sling box solo and I want to connect it to my TiVo. I currently am using hdmi cables and do not want to change to composit. I was wondering if I could use both RCA and hdmi at the same time. I'll only use hdmi with tv and RCA with streaming to my phone/iPad. Does this work? Thank you!
