The DCH3416 that I've been renting from Comcast for at least five years is acting up. When the backgrounded tuner is already on a given station from the last program it recorded and a new recording starts on the same station with the same tuner and some time having passed in between, the second recording is skipped, and there isn't even an error message (such as "fatal hardware error") in the DVR History folder.
So I got another DVR, intending to return the first one when I've watched everything already recorded on it and transfered all the programming for future recordings (one by one by hand, it seems; can't be done en masse through MyDVR) to the new unit. The Comcast service offices nearby had no HD DVRs available and the one shipped to me was the same model.
Thus, I now have two Motorola DCH3416s, one atop the other with spacers between them for ventilation, connected to the same television, one to the HDMI input and one to the component video and stereo audio inputs.
Comcast also included a remote, branded "Xfinity" instead of "Comcast"; both remotes have the classic silvery casing, but the old one's Select button is gray and the new one's Select button is red, in case that is significant.
I thought that if one unit is on standby while the other is on, any keys on the remote (except for Power) would operate the unit that's on and be ignored by the one on standby, but I'd forgotten about the Info key, and once I've pressed Info, I can't figure out how to get the machine on standby back into standby without doing something possibly destructive on the machine that's on.
We don't have any polarizing film around, and I hope to be done with the old machine and to have returned it in a couple of weeks, so it's not practical to rush out and buy some polarizing film (where would one even find that stuff?) just for this short period.
I've tried covering the panel of one DVR at a time with corrugated cardboard and with aluminum foil, but neither blocks the signal from the remote. Is there something else that would block it, which might be found around the house or be sold in a discount store or a supermarket or such? As it's only for a short time, I would settle for needing to move the blocking material physically from one DVR to the other.
Comcast tech support told me to try what amounted to changing the remote's code for the DVR to 00476; that had no effect and both remotes still operate both units. There would also need to be a step to change something at the DVR itself, perhaps by using the remote but by going through the service menus, wouldn't there?
Any assistance that doesn't require expensive or difficult acquisitions and isn't technically over my head would be very welcome.
