    I just picked up my HD Tivo, got it installed.

    I have to say I'm a little disappointed that the speed is no better than my Motorola DVR I had from TWC.

    I'm also VERY disappointed that there is no coax out. I have a tv in my bedroom that I was able to watch through my Motorola DVR that I don't seem to be able to watch with the HD Tivo.

    Anyone run into similar problems and figure out a way to watch on another tv? My other TV is standard def too so the RGB outs are not an option. They wouldn't be anyway as I have a Sony XBR450 and it does not have an HDMI input.

    Anyway if anyone else has run into this problem and fixed it let me know. Otherwise the Tivo goes back tomorrow and I will just use the Motorola as it's just about as good performance-wise and it costs less.

    Thanks.

    Why would you buy an HD Tivo to use with a TV that can only accept a coaxial input?

    I didn't fully understand everything, but it appears the OP has a Sony XBR450 HD Tv that only accepts component in (and other things, but no HDMI).

    He wants to be able to run component in to the Sony, and coax back into his home wiring and into another TV in the bedroom to be able to watch the signal in there (would have to watch the same TV show in both rooms).

    I think the bigger question here is whether or not THD will do multiple video streams out at the same time (same stream out on multiple video outputs) and I'm not sure if it'll do that or not.

    In either case, you wouldn't be able to view any of the HD stuff in the bedroom since it won't know how to display the HD content.

    IMO - keep TiVo for the XBR450 and keep the TWC DVR for the bedroom.

    If I understand your setup (not sure I do), you have a Tivo HD that you want to connect to your Sony XBR450 and to another (unspecified) TV in the bedroom.

    You can (and should) use the component cables (R, G, B) for the Sony along with audio R & W.

    The connection to the other TV should be composite (R, W, Y) or s-video if they are available. Also it would depend on the length of cable run needed.

    If the other TV does not have any AV inputs, you can use a RF modulator to convert AV signal to VHF over coax and connect that to the other TV.

    Changing channels on the remote Tivo, of course, would require a RF extender for the remote control.

    I think I will take a different approach - to me it sounds like his old cable company Motorola DVR was just passing through analog cable to a second TV. The only STB/DVRs I know of that are designed to feed 2 different TVs are Dishnetwork units and they have a second UHF remote for the second output.

    Thanks,

    Another thing to consider:

    You say that the Tivo is slow. If you just installed it, it could be busy indexing data. If so, give it awhile, and it may speed up. Also, the THD does not have latest software upgrades (8.3) that speed up the guide data. This should be upgraded in the near future.

    Wow thanks for all the replies :)

    Ok let me try to explain a little better.

    My livingroom TV (main TV) is a Sony XBR450 which is an "HD Ready" television. I can watch HD content on the tv through component input RGB or GBY whichever.

    My bedroom TV is a Sony but it is just a standard def television with a coaxial input in . I have a coax cable that runs from my living room to my bedroom that feeds that tv.

    The way it was setup before was the Motorola DVR which has a coax output was plugged into the XBR450 via component cables (HD) and I connected the coax running into my bedroom tv to the coax out of the Motorola.

    I basically got the exact same thing in the bedroom that I got in the living room (no separate tuner) but that that's what I wanted, to be able to watch my DVR in the bedroom on occasion. I have an RF unit for the remote control so I could control the DVR with a remote from the bedroom... (radio shack rf module).

    I want to do the same thing with Tivo, but it has not coax out. So it doesn't appear I can do it.

    I've read that some people had trouble with the converter having to switch the output of the Tivo to 480 everytime they wanted to watch tv on their standard def tv. I didn't have to do any of this with the Motorola DVR.

    So if that's the case I'd rather just go back to the Motorola as it's cheaper and does what I want.

    I wanted to get a Tivo because I had a DirecTV Tivo and absolutely loved it. It was fast and worked great and never gave me any trouble.

    This unit appears to have the same problems as the Motorola Unit. The response time for the menus and keys are really slow. And when you're on an HD channel forget it... gets REAAAAALY slow. I don't know why this is. I assume it's because they don't have enough memory in these boxes to handle the additional bandwidth but that's just a guess.

    Anyway if someone has successfully hooked up an additional tv with the same setup as me I'm all ears. Thanks for the help.

    Look at response #4, above; and:

    You can try out the Radio Shack one and return it if you don't like it.

    Ok sounds like all you need to do is add a RF Modulator near your TiVo and everything should work like it did with the Motorola. Connect the RF Modulator to your TiVo with composite video cables then connect your coax cable to the RF modulator and your remote TV.

    Example of RF Modulator:RadioShack RF Modulator

    I have a nearly identical setup to Imatk and came here looking for basically the same answers...I've got a cable company DVR that feeds an HDTV in my living room over component, and a standard TV in my bedroom over coax. I've been looking at picking up a Tivo HD but I had the exact same concerns. Even if you modulate it - can anyone confirm that the Tivo will output over both at the same time?

    For instance - I record a football game in HD. I go to play it. Currently with the DVR from my cable company, I'll see it in HD on my main TV, and standard def (widescreen with gray bars instead of black bars, 480i but correct 16x9 aspect ratio) on the bedroom TV at the same time.

    Can anyone confirm that the TivoHD can:
    * output over component and composite video outputs at the same time
    * downconvert HD programming (live or recorded) so that it could be watched on the composite outputs?

    You may be wondering "why record it in HD if you'll be watching in standard" but I use this all the time for tv shows that I would prefer to watch in HD, but often end up watching in bed as I fall asleep :)

    Thanks,

    -Tom

    Exactly Tom :)

    I usually watch TV when I go to bed just before I go to sleep.

    Tell you what I'm going to get that Radio Shack unit tonight and see if it works.

    If it does I'll post it up and let you know how it went.

    I figure it's only 30 bucks so what the hey.

    whoa!! get this one instead:

    buy.com

    it's a lot less expensive and i'm currently using it very successfully with my TiVo HD!!

    I had this same set-up (I think). I had a TV in the bedroom hooked up via coax, and HDTV in the living room hooked up via RCA out (now it's component cabling).

    I could possibly have run RCA cables all the way to the bedroom, but that would have stunk. HOWEVER, I did have a spare VCR laying around, which has RCA in, and coax out =)

    So right now I have the Tivo HD connected to the VCR via RCA cables. I have the VCR always set to tune to this channel (remembers that through a power outage, too). Then I have the VCR coax out connected to the same cable that runs to my bedroom TV.

    It was pretty simple, and since I never, ever use the VCR this works just fine for me. You could also do the same kind of thing with an RCA-to-coax converter, or I suppose buy some cheap VCR!

    Why can't you just use a splitter?

    The Tivo HD doesn't have coax out. If you want to connect with coax (like many of us do for various reasons), you need an RCA->Coax converter of some kind.

    Ok so I got the Radio Shack unit... thanks guys :) Works beautifully.

    HD channels look correct and SD channels look correct. I see all the guides etc.

    PERFECT!

    Thanks again for all your help.

    If you use a coax connection (OTHER than directly from the cable using a TV's built in tuner), you will only get mono sound.

    Sorry, that's not true. I suppose this could happen if whatever's converting the signal only supports mono, but most devices support stereo.

    It's very rare that any RF outputting device other then a cable box to output anything other then mono, they just combine and send, it's not financially viable for them to spend the money for the stereo encoding (which I believe also requires a license for the software)

    I'm with mattack, you won't get stereo on the RF.
    (and even then.. would it be worth it? )
