I just got the 15-1994 because I lost my vcr remote. My vcr is a Hitachi hffx-624. I found a code that works but the original remote had a program button and guide button. The 15-1994 only has one for both. Does anyone know of another setup that might work. My original is broke. Any help would be great.

Look up the advanced codes for this device. Maybe they're at

Look them up by the device code you programmed into your '1994 to control the VCR. Then look up the advanced code for the button that's missing.
Then look for the manual for the '1994 on the same site. Learn how to program an advanced code. Then set one of your smart buttons to this advanced code.
