Christoph,
Before I got your message, I had got out the old probescope ,connected a ir phototransistor to it and looked at the signal and realized the mceusb2 is not very accurate. The signal looks like 36khz but the lack of accuracy of the probescope it is hard to tell the difference between 36khz and 38khz. I did find that the signal header is 15 pulses of the carrier and then a space of about 10 pulses and each pair of bits was preceded by 6 pulses of the carrier. I got your message yesterday and and looked at the RCMM-32.conf file and it is exactly what I had found, except for the toggle bit. I used RCMM-32.conf as a template with irrecord. I had set the eps to 18 because of the in accuracy of the mceusb2. I would get a false recording sometimes but I corrected it manually. Below is the configuration that works.
I tested all the buttons except for the ones related to DVR options since the STB I was testing it with did not have the DVR options.
 
This is configuration is for the Motorola VIP 1200 and VIP 1216 STB provided by AT&T for their U-verse IPTV service

I don't know any hardware that is able to change the receiver frequency.
The frequency parameter in the config file only applies to the
transmitter.

Have you tried using the generic RCMM-32.conf file from the source
package?
