HD TV over coaxial cable with MiniBox
I, like many customers have been forced to transition from my basic "wall to tv" cable service to the Cox MiniBox. The MiniBox has worked well enough (despite being a horrible eyesore on my otherwise well organized armoire) while I was using the HDMI output, but I recently acquired an additional peripheral that requires me to now use the Coax option on the MiniBox (the new equipment uses HDMI only, and my tv only has 2 HDMI ports). So now, I am stuck with a 480i signal, despite the fact that I used to receive 1080i HD channels directly from the wall before the transition (over a coax cable, without the box). If I go to the Cox settings menu, it coyly allows me to select the "video output" option under "video/audio" settings, but then DOES NOT LET ME CHANGE IT TO 1080i, the ONLY option is 480i. So Cox has rigged their box to unchangeably default to 480i if you are using a coax connection, even though the coax standard is capable of carrying a 1080i signal flawlessly. I am assuming this is just another "horrible cable company doing horrible things because they're horrible" thing, but if anyone has any idea how to work around this without me having to purchase an additional device to convert HDMI to coax I would certainly appreciate it.
Also, if any Cox representative can give me a logical explanation as to why this problem exists beyond "we love making your life difficult" I would love to hear it, because you have done little to prove otherwise. This is not a hardware limitation, you could easily convert your signal to 1080i compatible with a coax output, but you choose not to, and that is truly aggravating.
