My old Xfinity 3410 (I think?) box finally died, and they replaced it with a shiny, new, larger capacity Moto RNG200N box. The box works great - except that now, when the HDMI cable is plugged into the unit, the component side only outputs 720x480. The old box would still put out 1080i out both outputs at the same time. If I unplug the HDMI cable on the new one that leads to my AVR, the component immediately jumps up to 1080i.
Because I'm lazy-ish and don't want to demonstrate my contortionist capabilities every time I want to record something using my Hauppauge 1212 (which doesn't happen all that often), I was wondering about the possibility of employing some sort of HDMI A/B switch box and running HDMI from the DVR into the A side, nothing into the B side, and just setting the swtich box to B when I wanted to record. First, is this enough to kill off some round trip notion such that the DVR will interpret this as the HDMI side being "unplugged" from the box? Second, is there a risk of signal degradation such that normal watching is going to be noisier or more fraught with handshake issues? Third, is there some better solution I'm just not seeing? It's not terribly hard to unplug the thing and plug it back in, and I only want to record something maybe every other week or so, but I just don't like the idea of constantly plugging and unplugging over time - and, like I said, I'm lazy when it comes to things like this!
