    The correct term for the Infra Red light source the TiVo uses to send control pulses to the cable box is "emitter" (or even "blaster"), not "transmitter".

    'Transmitter' is technically correct, though way too general. Anything that transmits an Infa Red signal can be known as an IR Transmitter. for instance, a remote control is also an IR transmitter.

    This is what I did. I have had tivo with basic cable for a year. I have Comcast cable in michigan. I recently recieved a postcard stating I can recieve a free Motorola DCT700 box with digital service free for 2 years. I don't really care for the box but I opted for it. After several unsuccessful attempts and several dollars spent on splitters and cables I have finally came up with a workable solution.

    I have a RF cable coming from the wall to the cable box. I have A/V (red, white, yellow) cables from the cable box to the input of the tivo box (i have series 2). Then I have a RF cable coming from the RF output of the tivo going to my TV. (A/V output from tivo to your A/V input on the TV works also) I went through settings and did the guided set up again like I did for the first time. I had some trouble with the IR connectors but the key is to make sure it is placed properly. The cable box's IR sensor is located about 3/4 of an inch from the far right side and also make sure the IR emitters are placed at least an inch in front of the cable box's sensors. When I made this minor change for the emitters, the channel changed almost immediately. The guided help finished with no problems. I can now watch digital channels with no problems.

    I hope this helps.

    I have a Tivo Series 2 with a Motorola DCT 700. Except for Channel 1 (On Demand) 2 through 99 are duplicated if they are offered (I have 2-77). They differ only in that one is labeled Cable and the other Box. Also Channel Changing is slow. Help appreciated

    Berkeley,...
    I was kinda stupid as I originally forgot to take the coax in cable from the tivo off and put the "splitter coax tivo side" into that plug and so I didn't have any digital channels working correctly (just said to "wait a Moment" until channels would come in).

    Once that was fixed, everything worked fine. If you follow the directions in the quick sart guide with the Tivo (especially when dealing with the S2 DT units), and you make sure to actuvate the DCT700 box correctly first (box and tv connected only with cable straight from the wall outlet and cablebox power straight from wall outlet as well, no surge/power protectors or strips being used) then you should have no problems.

    Connect a splitter to coax cable (from wall or whatever, I have 2 3-way splitters and a signal booster before this small 2 way split), have one side go to (coax) cable IN on Cable Box and the other to (coax) Cable IN on Tivo. Have A/V Composite cables from AV Out on Cable box to AV IN on Tivo. Then have AV Out from Tivo with cables to AV IN on TV. You can also add the extra COAX cable from Tivo's coax cable OUT to your TV COAX cable IN which will let you view whatever is the current (being watched) tuner on your tivo on your TV when using your main TV input setting on Remote Control (you most likely have it set to AV(1) or AV2 for actual Tivo viewing). If you have this connection, then when you put the Tivo on Standby mode, you should be able to change from AV on TV to TV mode and watch any of the lower analog channels while Tivo is in standby and possibly recording 2 other shows on the 2 tuners.

    As for setup of the box, I just chose the Motorola choice, and said it was digital. When doing the Tests for the IR settings, they initially would change the channel but not to the correct one, and then once it would test trying to change to specific channels (several different ones in a row) then it would work fine. I did not have to stuggle much with the IR Blasters on the box even though the box is so small and not even square/rectangular shaped, I put them infront of the IR dot inside, but slightly to the left as one of the "feet" on the bottom of the unit prevented it from having the bottom located blaster piece from sitting right over it. Both are about an inch infront of the unit with the 2 blaster pieces touching each other, and kind of resting against each other to hold them in place. This does not affect the channel changing, it does this just fine with either my Tivo remote or the Comcast remote, and I have no other IR blasters being used around the apartment at all so I didn't bother to make a "tent" for it as the box seems to change channels just fine without one there.

    It has no problems with changing channels to 3 digits numbers like 503.

    I have another cablebox Motorola (DCT2000 I think) with the Humax Series 2 unit we have (DRT800) and it seems to be pretty much the same except that it is smaller and doesn't have any displays other than the the Power and Messages LEDs on the front. My other box works with Serial connections so that is easier, and would love to have that on the DCT700, plus an option for at least Component AV instead of just Composite AV plugs. We also have a Series 3 with cable cards and cable cards are more of a hassle, had to buy a new Tivo so I could get the cards to work properly without losing premium channels.

    My Humax DRT400 is connected to my (or RCN's I should say) DCT700 via coax, and I have no problems. I used Motorola as the cable box brand. Would I get better picture using the composite out from the DCT700? I always thought coax had more bandwidth than composite. My TV is connected to the Tivo with component.

    Composite might be marginally better, it bypasses the TV tuner in the Tivo. It's just baseband signal vs. signal modulated on channel 3. Also you might have to use it this way to get stereo audio as the DCT700 likely doesn't have MTS stereo output.

    Both cables are probably the same amount of bandwidth and it's completely irrelevant anyway as you are only looking at the signal in one 6Mhz channel, a tiny fraction of the total bandwidth.

    Composite cables are coaxial; it's just different types of terminators, RCA jack vs. "F-type" screw on connectors.

    Composite has slightly more bandwidth, since it doesn't have an audio subcarrier tagged on. Plus the RF from the cable box will have mono audio, using the A/V connections will let you use stereo audio.

    Ah, OK, thanks a lot guys. I didn't even consider the audio aspect of it. I made the change, and it does look a bit better, and sounds a LOT better. :up:

    I got my crappy little DCT700 set up and working with my old workhorse Series1 w/ Lifetime. I was just wondering if there was a code to change the channels a bit faster... Set to Motorola 00093 FAST seems to work...but not fast at all... I can't imagine what the SLOW setting would be like...

    any suggestions

    Wow thank you so much for the 00093-C IR code, that worked perfectly for me! Without your post, I'm not sure I would have found it! Thanks!

    I've heard that the 100046C (or B) code will work better along with setting to send the ENTER key

    For the DCT700 I found that using the "General Instrument" box type to yield better results than "Motorola" when going through the ir guided set up. It's much faster and more accurate (no digit dropping).

    and it all went fine but this is what's happening.
    I used to put my Tivo on stand-by to watch live TV (I don't have a dual tuner or an RF splitter) but NOW......w/ the TIVO in the stand-by mode......it still changes to the channel to record.
    Has anyone else had this happen? And if I change the channel to watch live TV, then THAT's what is recorded....all the channel changing and such.
    Thanks for any input.

    Get a splitter. One end should feed cable box, then AV cables from cable box->Tivo and Tivo->TV. Other end feeds TV directly, change channels using TV remote.

    DCT700 connected withA/V cables. Works fine but the Guide won't update. Shows wrong channels and only a few at that. Been thru the setup several times with no luck. Suggestions appreciated.

    Sorry to bump such an old thread, but maybe you guys are subscribed to it and can help me.

    I have an old Series 2 Tivo with lifetime support I'd like to use for recording SD shows. I have a dct700 cable box from Verizon FIOS, which is digital-only. The Tivo works with the TV just fine, and the dct700 cable box works with the TV by itself, but when I try to put the dct700 inline with the Tivo, I don't get a picture. I've tried RCA cables and coax, both together and separately.

    Oddly enough, the cable broadcast is viewable on the TV if I hook the RCA into the Tivo's OUTPUT jacks, but the signal is jumpy and I can't see the Tivo messages consistently.

    Any ideas about what's going on here? Perhaps my cable signal is too strong, or my aging Tivo is broken somehow?

    My Series 3 with cable cards work just fine but I'd really like to get some use out of this older equipment. Thanks for any advice!
