I was searching through your database and found a helpfull post that has partially solved my problem. I`ve gotton the power button to work, just not the volume. The learning process must be done this way:

(copied from another post)

"If learning is not working.... I suspect you are not doing it properly, most likely because the printed manual is hopeless.

Here's the correct learning method...

1) Position the 2 remotes head-to-head
2) Press and hold the SET button, 2 flashes
3) Type 975, 2 flashes
4) Press the relevant device mode button (eg, TV, VCR, etc)
5) Press the URC-8810w button that you're programming. At this point the red LED will start flashing rapidly...
6) While it's still flashing, start pressing the button on your original remote. At this point the URC-8810w red LED will stop flashing, but KEEP PRESSING the original remote button until the URC-8810w's red LED gives 2 short flashes.
7) If you have more buttons to program, repeat steps 4 thru 6.
8) When you're finished, press and hold SET and wait for 2 more flashes."

This was exactly the problem. The key is to have the two remotes head to head at the beginning (step 1) and most importantly, to press the button on the original remote WHILE the LED is still flashing (step 6). The manual is very misleading in this regard. I'd be surprised if they don't get a ton of these returned.
