My 10-250s finally died and had no choice but to get DTVs HD DVRs. They sent me two H20s for free to tie me over until the new HD Tivo units come out. Everything worked fine for a couple of weeks, but now one of my H20s isn't responding to any remote, or responds very periodically. The other one works fine. I've changed batteries, re-powered the unit to no avail. Neither DTV remote works the unit, so it's not a remote issue, I don't think. I'd hate to think I have to switch out the box. Changing the channels on the front of the box works fine, but obviously not very practical to do this on a regular basis. Is this a known issue with H20s and their respective remotes? Thanks for the input.
