Strange problem with MRF-260
I've had an issue with my URC setup for a while which I always assumed was interference, but now it seems like something potentially more basic. I'm using an MX-1200 with a single MRF-260 that controls:
Denon 3311 (electrical cable)
Panasonic ZT60 (IR stickon)
Tivo Roamio (IR stickon)
Oppo 103D (electrical cable)
I have no trouble using the system with the Roamio, everything works well and I control the TV, the Receiver, and the Roamio all through the MRF-260.
But, if I start my Oppo macro/task, everything starts up fine and I can control the Oppo with the remote (still may need to tune the repeats as I sometimes need to press a button twice), but while working with that task I cannot send any signals to either the Receiver or the TV.
I used to have the same problem when I had a PS3 in the loop and was using the Logitech PS3 adapter. Whenever I was using the PS3, I couldn't control any of the other devices. At the time, I assumed that the PS3 was just putting out too much noise and the receiver was not receiving the signals from the remote. I never bothered to debug that as I never used the PS3 much (with the remote), but I'm getting the same symptoms with the Oppo now and I use that much more.
I would still believe it was interference, but when I send a command to the TV, I can clearly see the IR sender blinking on the TV. Signals are being sent to the TV, but they just don't register. It's hard to say if signals are being sent to the Receiver since it is using an electrical connection and so there is nothing that blinks when it gets a signal. Also, worth noting, is that I cannot send any signals to the Roamio in this state either (starting the Roamio task/macro doesn't power on the Roamio).
If I turn off the Oppo using its front panel power button, then suddenly all other device connections start working again.
So, is this still potentially interference even though I can see the signals getting to the TV's IR stick-on? Is a Blu-ray laser a prime candidate for causing the interference (seeing as it happened with both my PS3 and my Oppo)?
Is there a way that the electrical connection that I've been using to connect to the Oppo (and the Logitech PS3 adapter before that) could be blowing the MRF-260's mind when that device is powered on?
I've seen a lot of recommendations to stay away from the 260 and go for the MRF-350 instead and I'm pretty close to just trying that solution, but I'm wondering if there are other things to try before I bother swapping out what appears to be a perfectly working component other than this odd "IR signals aren't recognized when a 3rd component is on" issue.
