No, I was just too tired after my adventures with the HR20 and AVAtrix last night to get on here and post my results. I did move the HR20 into my equipment closet and hooked it up to the AVAtrix. Currently the only TV I have hooked up through the wall plates is in my son's room, so all my testing was done in there. His room is 10x10 or 12x12 (pretty small) and the TV with a dinky link 48085 IR receiver attached to the bottom of his Syntax Olevia LCD TV is on one wall of his room near one corner. I was about 6 ft away from the IR and used the standard DirecTV remote that came with my HR20. My AVAtrix is on whatever the newest firmware was as of 2 or 3 weeks ago.
When I pointed my remote directly at the IR sensor, I rarely got any response (the IR recevier was lighting up each time, so it was receiving the signal). For instance, if I pushed the channel up button, it might work once out of 20 times. I did eventually get into the menu system and the down arrow seemed to work about 70% of the time, but the up arrow did not work. I definitely could not use the HR20 with this performance.
I used the AVAtrix remote to rotate among the various sources and it worked every time without ever dropping an IR request. I also tried my standard DirecTiVo peanut remote with one of my HR10-250 sources and it responded to IR signals > 95% of the time...same as I have seen before that it will work almost all the time, but occaisionally misses something. Probably just a little bit worse than if I was pointing the remote directly at the unit.
Just before giving up for the night I decided to point the remote at the back wall of my son's bedroom (180 degrees from the TV/IR sensor). The HR20 responded. I kept pointing it at the back wall and got about the same >95% success rate that I see with my HR10-250. This wasn't real convenient, but at least it was working. Next I tried pointing it at the ceiling and again it worked well...basically if I did not point it directly at the IR sensor I got good results.
So with my limited testing and knowledge, it appears to me that the sensor is getting flooded with the IR signal from the remote if you point it directly at the remote. Maybe it is in the "receive" mode too long and is picking up both the direct IR signal and the bouncing IR signal if you point the remote directly at the receiver. I ran out of time, but want to try the masking tape method and try a universal remote instead of the stock HR20 remote to see if that makes any difference.
Trent, with so many of us having problems with the DirecTV HR20/21 is there any chance you guys can test this out at your facility to see what we can do to get this to work? I would guess that most of your AVAtrix customers who have DirecTV have this DVR or will soon have it as the HR10-250's get phased out.
I'll post the results of tonight's test later.
