    I am researching the same issue as I am trying to connect 2 TV's to my Roamio Plus. One via HDMI and one via Component. The HDMI output works fine but I don't get any signal on the Component side.

    I found this seemingly official response from a Tivo support person:

    "because the TiVo Requires an HDMI handshake from the TV trying to send recieve the TiVo through a third party device would not allow the TiVo the ability to display picture."

    http://forums.tivo.com/pe/action/forums/displaythread?rootPostID=11156626&nextElementId=11146222

    That seems to imply this won't work or am I missing something?

    Should work. Not familiar with anything on the component side that would prevent content from being displayed. The only way I can make sense of that comment from TiVo support is if HDMI is connected to an intermediary device that doesn't support HDCP. This wouldn't apply to an analog component connection.

    Do you get a signal from component on the other TV assuming it has inputs?

    I tried Composite on mine and it worked. For Component you may need to disable the 1080p modes. I don't think Component is capable of 1080p/60 or 1080p/24 so that could be what's causing the problem. You probably have to drop down to 1080i or 720p for it to work properly.

    Component works with 1080p/60 for me. Some TVs/devices don't support it but the TiVo does output it correctly.

    From responses above I understand the Roamio basic simultaneously outputs both HDMI and Composite signals.

    My problem is I just upgraded from an old series II Tivo to the Roamio basic DVR and went backwards in terms of functional use. My old set up allowed me to send Tivo recordings via coaxial to our old TV in the Kitchen which kept my wife happy when cooking. The new HD box took that feature away. Has anyone tried taking the Roamio composite output signal back to a coaxial connection via a RF modulator allowing an older set with only Coax input to view the DVR?
    PS: We tried upgrading to a flat screen but her food prep area had viewing angles made the flat screen image not viewable.

    Get a better flat screen there, one with a wider viewing angle. None are likely to be quite as viewable as an old-school CRT but some of the plasmas come very close.

    If it's composite (the yellow plug) then you should be able to use any old RF modulator to put it on an RF channel. Channel Master (and others) used to make RF modulators that would let you select which channel to use (besides 3 or 4) along with supporting MTS stereo.

    Thanks for the quick response. I'll try the RF modulator I see eBay has several. I may try a TV upgrade again. Our problem is location and size. The 12"crt is perfect size for her food prep area as she is viewing within 2feet at angles greater than 60 degrees. Maybe a LED model would work better.

    Seems every time we try to advance on the tech scale we lose functionality or it doesn't work at all. We both kept laughing when we replaced the CRT with the LCD as it was totally worthless in our application.

    Received the RF Modulator and composite breakout cable today hooked them up to the Kitchen TV will still using the HDMI output to the FR Flat screen and got no composite signal out of the TIVO. Rewired the Roamio composite output to a known good input connected through a VCR feed no signal from the Roamio.
    Hmmmm....Called TIVO support, official response:

    "Roamio does not support dual HDMI and Composite outputs simultaneously, it's one or the other"

    Whaaaat.....everybody on this forum says they're using both outputs.

    So I go through tech supports system checks and we confirm that my brand new Roamio out of the box has a defect composite output. They had me power down disconnect the HDMI cable leaving only the Composite output connected power back up and still no output.

    I guess my concern at this point is TiVo says that the Roamio box looks for a handshake with the HDMI and based on this handshake response or lack of it turns on the composite output. I know TiVo is pushing Mini's with a monthly fee and that could be their reason for the response I got.

    My question has anyone else had this issue or did I just get a bad TiVo box?

    Update
    Turns out two TiVo Tech Support agents have no idea how the Roamio composite output signal really works. Also turns out my new Roamio box is ok, all I had to do is swap the breakout cable's yellow RCA plug with the white RCA plug and my Composite output worked fine as well as my HDMI output.

    Apparently, even though TiVo tech's say any breakout cable will work on the Roamio what they didn't say is that you just ignore plug colors as Tivo put the yellow video signal on the 3.5mm plug's tip rather than on the 2nd ring. All breakout cable are not configured the same, but prior cable mfg's never put the video on the tip. TiVo must have done this to sell $14.99 breakout cables. So my cables yellow is connected to the Tivo left audio and it's white is connected to the Tivo yellow video connector.

    Everything is right with the world now.

    Good to know, thanks. I've been considering rigging up an RF modulator on a composite output, if just to avoid seeing snow and hearing REALLY LOUD static when switching through inputs on one of our TVs. Practically wakes the dead when that happens. I love that new TVs tend to have the ability to disable inputs, but not all will do that for the tuner.
