Question for you guys. Im currently a mediacom customer and looking to shave down my bill. If i get a TiVo and want to use it only as a DCT (Cable box) and rent the Mcard from mediacom, is that an issue? i dont need the DVR ability as my son doesn't need to record anything nor does my dad. I was looking at this on amazon. TiVo Roamio HD Digital Video Recorder and Streaming Media Player (TCD846500) Before i order 2, i want to make sure it will work. Anyone else tried doing this before? My main needs are just the guide and the prem channels that im sub to. The VOD and the rest i could careless about it. Or even cheaper ideas.
