I have a 1TB external drive connected with the Motorola DVR Cable Box (DCH3416) for extra recoding space. I understand that the DVR works something like a hard drive in a computer and 'communicates' with the external drive, but what is happening is that over half the time remote control commands are 'hung up' .... ie-changing channels, switching to recorded shows listing, etc. don't happen at once, as if the DVR is hanging up the way a computer will sometimes. After a few seconds the commands will happen in rapid succession (like when you try to load a browser, get impatient and click several times, so you get several browser pages opening at once).
I've called COX tech support a few times and, depending on the familiarity of the tech with this issue, the answer varies from "it's always going to happen because of the external drive" to "switch out the box for a new one" (not my choice first as I'd lose everything on IT and the DVR itself).
Anyone have a more definitive (ie- useful) thought on this?
