Updated June 6th to include codes for both the RCA DTA800B and the DigitalStream DTX-9950.
Quick post to help others in a similar situation of needing to set up a CECB to be controled by a ReplayTV 3000 (Read subsequent posts by others to assist in setting up for other versions of the Replay that use different codes)
RCA Summary: Use IR blaster code 392, 533 or 5392 to control the it from the Replay!
DigitalStream Summary: Use IR blaster code 749, 819, 899, 8749 or 9749 to control it from the Replay!
Since I don't get locals with my DishNetwork package and the local analogs have always been less than perfect, I wanted to see what CECB's could be controled by the ReplayTV and have the locals integrated into the program guide somehow.
My situation: My replay had 2 of the 3 inputs used. RF for analog NTSC for locals, Line 2 for S-Video fed DishNetwork (no locals). Line 1 was unsed.
Basically to get it to work, I told the Replay that on the Line1 input I had a DirectTV (Local) box. I picked a prenamed box but it didn't work, so I manually configured the IR code.
For the RCA, I found that codes 392, 533 and 5392 all would turn it on or off during the setup menu. I left it at 5392 for the rest of my setup, so I don't know if 392 or 533 work better or worse.
For the DigitalStream, I found that codes 749, 819, 899, 8749 and 9749 all would turn it on or off during the setup menu. I left it at 9749 for the rest of my setup, so I don't know if the others work better or worse.
Then after the Replay downloaded the new channels, it placed them all at 1000 through 2000. I deleted everything other than my locals in that range.
All of my primary locals were already mapped to the correct channels. So selecting 1004 blasted 04 to the CECB causing it to switch to 04-1, and the Replay correctly switches to that input. Likewise 1015 sent 15 to the CECB switching it to 15-1. The guide lined up prefectly for the primary stations.
Of course, I have no ability to select the other sub-channels like 6-2, 6-3, 13-2, 13-3, since there is no mapping to a - button from the Replay, or anything that would have that encoded into guide information anyway.
Hope this helps everyone! Post to the thread with questions.
PS: I do not know what "brand" these IR codes actually relate to on the Replay. Does anyone have that info? Also I haven't yet tried to control the boxes directly using the CATV/VCR button mapping on the Replay remote either. I would assume this will be easy to set up.
Differences between the 2 boxes: The RCA was much faster to respond to selecting a new channel (within 1 second of the Replay switching to that input) than the DigitalStream which took about 4 seconds).
