I am on my fourth HR20-700. The last 3 are refurbs, and the last one ( a few days ago) has a 700CR model number. All the others were 700/700Rs.
I have made a bunch of posts about being unable to receive either 8-1 or 13-1 (NBC/Fox) after some of the recent CEs/National releases.
My OTA tuners originally showed 95+ for tuner 2 on both channels, and over 50% on tuner 1. After the updates, tuner 1 no longer locked onto signals for these channels on my first refurb (the original new HR20 was DOA!).
The second refurb was able to get the signals at 98+ on both tuners, ( using )x168?). and, I could see both channels again (as well as all the other locals in Tampa from the Riverview area). However, it had other problems (lockups, repeated spontaneous reboots).
The most recent HR20 refurb has been getting similar signals to the second one, and. so far, seems to be doing it's things just fine? This was on ver. 168, and, the CE this Friday. The original software on this unit was 0xbe. It was built in Dec., 2006?
Talks with tech support repeatedly resulted in asking me to wait for a "software" fix which they said was coming. Finally, they gave in. and, demanded I get a housecall. The tech said it was a hardware problem.
Seems to me that the tuners in my last 2 refurbs were/are better than the second one, and that my problem indeed was a hardware problem. I would guess that the change in reception noted after software changes was coincidental to increasing tuner problems?
I would be interested in opinions from forum members on this.
1. HR20-700-> (HDMI-> Samsung 5088 in media room with large "bowtie antenna in attic for OTA
2. H20-600->HDMI->Samsung 3251 in master BR, D* bowtie on roof for OTA
3. 5-LNB dish
4. Modulator from HR20->RCA cables to send DVD & D* to kitchen and other BR via cat5 wiring in house.
