"The numbers available should be enough to control the pace of the digits - you have a lot of control there, though perhaps there are timings involved that aren't under control. It happens only rarely for me. One possibility: a mirror or equivalent (window? even a wall) facing the box might cause enough reflection to confuse it. Testable by putting tape or cardboard, etc in front of the ir repeater. Another possibility: placement of the repeater."
This is not a signal issue. I can prove it to you. Find a few half-hour shows on the same 3 digit channel (a good example would be one with a zero at the end, say 170). Have replay record 5 shows in a row (doesn't matter if they're trash or not, you're not going to watch them). So go to channel guide, press record once on each show consecutively. no gaps, no chance to go to another channel. do this at 3am so it doesn't interrupt your shows if you must.
Now don't touch the replay. Don't watch any prerecorded things on it, don't use the menus, don't touch a thing. I found that using it in any way can actually make this problem not happen sometimes.
Set your watch for 1 minute before the end of shows. Still without touching the replay, watch the window on your cable box. Watch the pace of the digits as replay sends them.
it will send the first two very fast. It will then wait more than a second to send the third digit. So the cable box will change to channel 17, and then fail to understand a change to channel 0, and stay on 17, when you wanted 170.
It may take until the second or third show for this to happen.
After all 5 shows are recorded, go watch the first second of them (this requires saying "play from beginning" and then "instant replaying" back to the real beginning. You'll see the change to the 2 digit channel, then to the 1 digit! plain as day. giant space between digits.
No amount of tweaking the cusom parameters will fix this. I have two boxes, and i tried every working code and every permutation of short and long waits between digits on the boxes, recording what i'd done and what i hadn't. Every single one of them screwed up a change at one point.
I tried moving the IR blaster further away.
I tried fortressing/tenting the box (making it so that no light other than the IR blaster could get in).
none of this works.
The device i built to take in the IR from the replay, clean it up, and pace it out to the STB works perfectly. every.single.time.

It is as simple as this: There is a bug in the replay transmission code. Sometimes it takes too long to send a digit. The motorola boxes do not wait long enough to get all the digits, and there is no changing that.
Jdibb: I have signed up for a faster package than i previously had with optimum online. I pay more money. It does not go faster, even on speed test sites. I do not have a software firewall, as i don't think they're of any use.
