I have a puzzling problem with an upgrade that works fine on one model remote, but not others.

I used a URC-8910 learning remote to learn all of the original buttons from my HP Plasma TV. I then created an upgrade in Remote Master and uploaded it to the URC-8910 with IR.exe.

When I use the URC-8910 remote in the learned button mode, the TV will work fine for that learned button. The IR signal is received fine from up to 20 feet from the TV and off to the side. The URC-8910 works fine in the learned mode.

When I upload the upgrade file to the remote via the JP1, it works weakly. The remote has to be about 6 or 8 feet from the TV and not far off to the side. Sometimes it takes multiple button pushes to get it to work.

I then created an upgrade for my RCA RDU-810. It works weakly like the URC-8910.

I then created an upgrade for my URC-8080 B02 Producer 8 and uploaded it to the remote via the JP1 and it works perfectly. It works from far away, off to the side, etc. Does the URC-8080 put out a stronger IR beam?

Here is a link to the upgrade file I created for the URC-8080 B02:
