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.

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.

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  

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.

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

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 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?

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.

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  
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.
