I've got a RU940 that died after I spilled a cup of tea on it so I decided to use a 5450 until I could get a replacement.

What I've done is convert the RU940 ccf to a TSU6000 ccf then upload it to the ipaq running pdawin.

And that's where the trouble starts. Some of the buttons work but many (especially for my Panasonic TV) don't. It doesn't seem to be a consistent problem either as the red, green, blue buttons don't work, but the yellow button does. Also, when I try to teach the buttons that doesn't work either. In fact, it's stranger than that. I can teach the yellow button (the one that already worked) but the others don't work after teaching despite the process appearing to work.

What the hell is going on?
