    After the previous thread, I'm interested in a set-top box... oh, that
    includes the roku that I asked about before on one of these groups.

    Well 2 more questions:

    The descriptions keep talking about HDTV. One doesn't need HD does he?
    It will output to SD also?


    Are some of them wireless and can I expect it to stream continuously
    with wireless B/G? Or do I have to buy a new router with N?
    Remember, I don't have HiDef, and I don't expect to get it. If I buy
    with AC, will it still suppport B/G, which all my other devices are?

    And if you want to use one of these boxes with a smart-cell-phone app,
    that means sending data tot he phone company and getting something back?

    Or is it all within the room one is sitting in?

    A 54G will be fine , I streamed all kinds of video and audio sometimes
    simultaneously . And just because HD content is available doesn't mean you
    have to use it - your old CRT TV will be just fine . What kind of cable are
    you going to use from the ROKU to your TV set ? Mine has only component and
    HDMI outputs ... no RF hookup .
    Right now I'm watching Rush Hour from a DVD in a computer - I have 4
    inputs hoked up , Roku and the comp on the HDMI inputs , a DVD player on the
    component (yellow/red/white) and the satellite receiver on the RF input .
    BTW , you really should consider a newer TV , we got a 32" LED/LCD last
    spring and just love it . You can get a pretty nice unit for under 300 bucks
    , often nearer 200 if you catch a sale . Available inputs are going to be
    the biggest problem with older TV sets ...

    It is not the mode whether G or N or AC. It is a matter of minimum
    constant download speed is needed for good media viewing. I'd say
    at least 5mbps and up. No one likes stuttering video/audio. I have
    50/3 service from my ISP. Always I can have download speed ot 50mbps.
    I real time stream always.

    The Roku or whatever will probaby input to the DVDR, which already
    connects to the TVs via composite, left, and right RCA cables into a RF
    modulator, and from there via co-ax to all 8 tvs (with a couple of RF
    amps along the way.. I found that every two splitters I have to put an
    amp.)

    There would be a possibllity of using Y-connectors and going into the RF
    modulator directly, but I think the first way, I can use the channel
    selector to select the Roku when wanted. There are "channel
    selectionss" for the set of jacks1, set of jacks2, and set of jacks on
    the front of the DVDR. And I have remote controls on all 3 floors,
    with transmitters that get relayed to the DVDR. Not installed but I
    also have a remote controlled A-B switch, but only one remote for that.
    I'd probably end up having to walk upstairs to change from DVDR to Roku
    If I could just buy one TV with wifi and a digital tuner and all those
    inputs**, I'd do it, but what I need is an output to go to the other tvs
    in the house. If I had it to do over, I might have run left, right,
    and composite everywhere, but too much work for me now. What was
    especially hard was snaking the co-ax though the ceiling of the basement
    "family room". Down 6 inches and across 25 feet, to the laundry room
    with no ceiling. Maybe I used two snakes. But I made no provision
    for running more wires so it would be even harder to do more wires now
    than it was to do one wire the first time. I know there is wireless
    transmission, but then I'd need 6 or 7 receivers (I rarely use the tv
    in the attic these days, mostly for aiming the attic antenna.) ,
    including one in the bathroom where there is no room, and wired is
    certainly reliable. I"ve had those 2 signal amps running 24/7 for 31
    years without a problem. But better to have 2 power amps running.
    they don't use much power, than to have 6 receivers running.

    **Even the big ones only have speaker outputs and maybe unamplifed sound
    outputs (to go to the stereo) but I only want a small TV in the bedroom
    where the DVDR is, and they usually don't even have speaker outputs
    (although they need them the most.) . In the bedroom I use the earphone
    jack but run it to a mechanical rheostat (mounted in a Pong remote
    control box), and from there to an amplifiied computer speaker. So I
    can control the volume with a knob instead of having to use the remote.

    But G is slower than N which is slower than AC, so I think the wireless
    too can bottleneck the signal. So I think the mode does matter.
    Except Terry tells me that B/G is fast enough.

    But even if the output connector is, say, only HDMI, it can still be set
    to output a standard definition signal, can't it? What if someone
    has one HD tv and another SD tv? Does that mean he can't use the
    expensive box?

    IMO, G isn't fast enough for me and you are correct, AC is thus far the
    fastest but here's how it works. If you have a G router, any other
    device with G/N/AC capability will only use G. If you have an N router,
    any device with G/N/AC will use only N and of course, if you have an AC
    router, any device with AC capability will use AC. If a router has AC
    capability but a device has max of N, it will only use N. Bottom line,
    BOTH devices require the same capability in order to meet the speed they
    advertise.

    Also keep in mind, even if you have the fastest router and device, your
    speed will still depend on what you're paying your provider.

    Make sure the box you get has SD output. There are converters (HD to SD)
    but they can be expensive.
    AC uses a different frequency than B/G, however all the AC devices 've
    seen support both frequencies. AFAIK N can use either frequency.

    Always consider a WIRED connection first. It's simpler and more
    reliable, as well as more secure.

    Check the specs of the specific model of the set-top box. Some newer
    ones only have HDMI outputs. Other newer ones have both HDMI and
    composite video.
    Again, check the specs. Most newer ones are retro compatible with the
    older WIFI standards.

    Just don't buy a set-top box without consulting the specs and you won't
    have an unpleasant surprise. And again, to emphasize, different models
    from the same manufacturer often have different specs.

    To summarize, OP has to look at both ways. What you have and what you're
    connecting to it. Simplest is HDMI but there are converters
    like VGA to HDMI, component to HDMI, display port to HDMI, etc. If
    not carefully planned, hook up can get very messy. Easiest is get a
    entry level HT receiver with speaker kits in a box. Then A/V receiver
    becomes hub of every thing. Every thing connects to A/V and one HDMI
    cable to TV set.Older A/V receiver can be had for like ~100.00. You can
    have simple stereo set up with two speakers and start from there upto 7
    speakers plus two woofers. Surround sound is nice to have. WiFi mode is
    downward compatible.

  12. Tony,

    Not all home theater receivers provide video output in a different
    format than the format of the video input. My home theater is a Best
    Buy Insignia unit - which came with all the speakers; a unit that meets
    your description of "entry level HT receiver with speaker kits in a
    box". The receiver appears to be a re-labeled Onkyo unit. I have HDMI,
    component, and composite input sources connect to the HT receiver.
    However, I found to my surprise, consistent with the user's manual, that
    the receiver outputs those video sources only to the same format output
    jacks on the receiver. Fortunately, my HDTV has sufficient input
    sources of each type so I don't have a problem. In summary, my HT
    receiver won't output a composite or component video input signal to the
    HDMI output jack. If an when I ever replace my HT receiver, I'll make
    sure the replacement can do that. Peter

    Your only choice is then using little converter box. 3 cable component
    cable/digital audio in and HDMI out. Some time ago wife won a HT in a
    box, LG brand in a raffle. It has HDMI o/p to HDTV. Since we did not
    need it, I sold it to a neighbor's kid for 100.00. I never like Onkyo
    receivers.
    Their power supply seems to be little under rated. Unit runs always too
    hot to my liking. I was a fan of Denon stuff. Now I moved up to Anthem
    receiver and all Paradigm speakers except PBS 250W 12" Woofer. When
    organic TV price comes down I'll upgrade TV set.
