Hello a newb hear.. so be nice... LOL

I have a 37 in Westinhouse LCD TV. My cable service is Brighthouse Central Florida. My box is an Atlantic Scientific HDTV DVR.

I was wondering if there is a way to synch up two televisions. I have a 19 in outside that is at least 3 seconds ahead of my LCD tv inside. I don't mind it for the most part but when I have people over and they are outside watching the same game we are watching on the inside... u know something happens cause they alway cheer or grumble before we get to see what happens inside. It is annoying and disappointing casue you know something is going to happen and takes away from the thrill of watching the game.

Does anybody have any suggestion to remedy this problem.

Oh yea, and I do not have a cable box hooked up to the TV outside. A) Nowhere to put it, and B) Don't really want to pay the monthly fee for a box outside.

Not likely unless you run a video and audio feed out from the ouput of the DVR to the other TV......

I dont know about your area but most HD DVRs as I have seen in the Midwest Area cease to offer you the ease of a coax ch 3/4 output that would be easiest for you to run. Plus that picture would be nice for something like this but defeat the idea of HD anyway.

If you do have this output run a coax from that to the tv outside and the box will operate both tv's at the same time with the same delay.

Run the coax into another antB input on the tv if it has 2 or use an A/B switcher to make switching backand forth to regular cable a breeze.....


Be careful if your nextdoor neighbor is watching the same game, youll be able to hear him cheer and grumble and then he'll ruin the game for everyone being 3 seconds ahead....Just kidding on the last part.....

Yeah, I think the delay happens in the DVR, so you would have to feed the outside TV from the DVR. I am doing this myself with one of those $20 modulators that gives me the DVR output, but 480i and on channel 3. It isn't high def, but it's a damn good looking low def!

Some DVRs don't put out 480i while putting out higher rezzes, though, so you have to look that up before you know if this could work.
A good answer is easier with a clear question giving the make and model of everything.

Definitely the DVR's fault. They are always playing a couple seconds behind to allow for constant recording of live TV.

The delay is 4 sure related to the hdtv processing, modulate the signal from the composite out is the only way. It the same with directv, comcast, whatever.
Anyone know why the composite out of comcast box shows hdtv in correct aspect (with black bars on top,bottom), but directv composite out distorts hd into 4:3?

A quarter second might possibly be HDTV processing, but he said three seconds! That couldn't be processing, but has to be delay between the signal going into the DVR and signal coming off the hard drive. It really is probably only one or so seconds, but it still is way beyond the delay that processing would introduce.

Processing is usually minimal, from nothing to maybe 1 or 2 tenths of a second on older equipment. The DVR delay is purely a signal recording/playback thing, although some do have a "live" mode that is more live than others. :-)

Press the "live" button, this may help but it won't sync up to other tv's due to the DVR buffer.

How do you like the Westinghouse 37" LCD. I installed one the other day and I have got to say it was pretty bad. I installed a SD DVR and a H10 HD both by DirecTV. The HD looked ok. I am not sure what the contrast ratio is, but it looks like 500:1!
It takes 2 to tango, but only one to be nice!,
