I've got the PM725, Philips Magnavox universal remote, and I'm having trouble going into learning mode. I was able to earlier last night, but now I can't. I hold Code Search, and it stays red, hit the DVD button, and it blinks once, but then when I hit Learn, it flashes and turns off. I thought maybe clearing the learned commands would help, but it won't even let me do that: Code Search, stays red, Learn once, blinks and goes off. If there is any other way to erase every code it's storing and start over, I'd appreciate knowing what it is. Or, if anyone knows what I might be doing wrong, please let me know.
