    I have an Onkyo tx-sr503 hooked up to my Tivo Series 3. Last night, the a/v volume and mute capability of the tivo remote quit working. The batteries are known good. Everything else on the remote works fine. I can see the lights blink on the tivo when trying to change to volume, but nothing happens. I tried using different codes for the Onkyo. I've restarted my Tivo. Nothing seems to work.

    Just wondering if anyone else has had this type of issue. Any advise would be much appreciated.

    Don't know what the problem is but it has nothing to do with your TiVo, thus no point in rebooting it etc. The blinking light on the TiVo is at least telling you the remote is putting out a signal.

    I assume that the Onkyo is connected to the Tivo by either a HDMI or Toslink cable. Try re-seating both ends of the cable. Maybe they have become somewhat dislodged.

    UPDATE: What was I thinking? jbernardis, below, is right.

    The av and power functions go directly from your remote control to your AV receiver. When you use the tivo to program your remote, it is only guiding you - the actual programming is IN your remote. Rebooting the tivo, or reseating cables, will have nothing to do with it - the Tivo is not involved at all.

    I can offer no explanations for why it's happened, but if it happened to me, I'd try going through the remote control programming steps again.

    Rummage through the couch cushions 'til you find the original Onkyo remote and see if that works on the Onkyo.

    Although it probably needs new batteries by now.

    Thanks for all the replies. I have successfully diagnosed the problem. Apparently, the volume and mute features don't work with certain types of NimH rechargeable batteries in the Tivo Remote. I know it sounds strange, but I am able to reproduce the behavior. With Sony NiMH rechargeable batteries, all functions of the remote work except mute and volume control. When using Sanyo Eneloop rechargeables, all remote functions work like they should.

    Thanks again for the posts.

    PS- I highly recommend the Eneloop Batteries. Rechargeable battery technology has come a long way.

    Perhaps because the TiVo remote was designed to use regular non-rechargeable batteries, which have a little more "oomph"*


    Regular batteries are nominally 1.5 Volts, and rechargables nominally, if memory serves, 1.2 or 1.3 V.

    And then there may well be a difference in internal impedence as well.

    You've found an instance in which the Sanyo batteries outperform the Sony in a device and application designed for neither.



    *That's one of those highly technical terms.:)
