    Just when I need them I can't find them - my cable company is switching to all digital and I now need my IR blasters.

    Any suggestions on a cheap solution? I went to Best Buy and they couldn't help and Radioshack suggestions a solution that cost $45!

    Thanks for any advice, or if anyone has a pair they'd like to send me :)

    Happy 4th of July to those that celebrate.

    Not after tax and shipping.

    The cost from Tivo is $15.02.

    The cost from Amazon is $18.99.

    If you bought another $10.01 of merchandise from Amazon along with the emitter, the cost is 3 cents cheaper.

    I'm pretty sure you can use any IR blaster, when I was doing some research I was able to pick one up at either Best Buy or Target actually. Amazon may be cheaper, but if you're looking for a quick test/fix, that would be my suggestion.

    Another option is to check craig's list or yard sales. I've bought a few tivos just for the extra remotes and ir blasters. Then you will also have a spare hard drive and power supply.

    If you can solder, they are very easy to make. Just get a 1/8" mono plug, some small gauge speaker wire, and an IR LED. Hook it so LED +(anode) goes to the tip, and LED -(cathode), goes to sleeve. I have made one or two of my own, and they work great.

    Any trick to getting them to work well? Sometimes I get the wrong channels when on my former cable box. Should they be placed close to receiving light?
    Also I now have a very small digital cable box I haven't fixed them to yet. Do they work on that?
    I've just been turning the channel manually!!

    IR blasters work with the Comcast Digital Tuning Adapter and a Series 2. I got a direct cable on ebay that works perfectly.

    what do you do with a 'direct cable'?? Not sure what that is.

    HDRyder9 may be referring to the cable that goes into the thing on the back of the TiVo that looks like a modern-day headphone jack that isn't the one that the IR cable goes into.

    Those jacks should be labled IR and Serial.

    The one that goes into the Serial jack has one end that's a 1/8th inch (3.5mm) tip-ring-sleeve plug, looks just like a stereo headphone plug. The other end is a 9-pin "D" shell RS-232 plug (looks like a VGA plug with fewer pins). That end is for some cable boxes and/or satellite receivers that have serial ports for external control.

    AFAIK, only some of the DCT2000 series boxes have serial ports usable by TiVo, if the provider enabled them.

    The DTAs have no serial port, but have an input for an IR receiver. With that, you can get a cable made by Gary Gray (called the GGray DTA cable I think), which links the TiVo IR blaster port to that IR input on the DTA box.

    If this will work, it's only $2.88 + shipping.

    FTR, monoprice is typically the cheapest place for anything that involves a cable. They are also really cheap on ink and toner as well.

    This cable is an extender, not an emitter. It won't work

    In the big version of the picture it looks like it has a plug at one end and an LED at the other end which has an arrow pointing out and "TX" (which usually means "transmit") on it.

    I'm puzzled by why it has a tip-ring-sleeve 1/8th inch plug instead of just tip-sleeve, though.

    Nothing more than semantics. They're both the same in this case. It's a mini phono jack that plugs into a serial port with an IR LED at the end of the cable. It transmits an IR signal fed to it via serial connection. The item from Monoprice should do exactly what the OP is asking for.
    Check any serial cable used with a Tivo and you'll see that they all have the same configuration. The three connections are for transmit, receive, and ground.

    But this isn't a send and receive serial cable, it's a send-only IR cable.

    The TiVo IR cables have a "mono" plug.
