I've been a long-time TiVo user - my first TiVo was a Series 1, and I've had several Series 2 boxes, and most recently, a TiVoHD. Just finally bit the bullet and bought a Roamio Plus. Got it set up and have been exploring. Looks like it might have a lot of neat features. For example, I discovered in the Opera store I could play "on demand" a bunch of the 1960's Speed Racer cartoons - really cool to a kid who grew up in the 80's... I found out while researching the Roamio that I could activate an MLB.tv subscription on it so I could watch the Chicago Cubs everyday - a great thing for this native of Chicago who now lives in Ohio. What other features should I know about? Is it possible to use any of the "on-demand" free channels that Time Warner offers (and show up in my list of channels) or do I need a "true" cablebox from them to be able to see those? Any help in using our new Roamio to its full potential is appreciated!
