I don't know, whether RCMM works with the Nexus 2.1,
but maybe the following will help you to find out...

The remote control codes will only be passed to the driver if you select 
correct values for protocol and inversion setting.
Furthermore, the codes will only be passed to the event interface 
(remote control plugin) if you load a correct keymap.
Otherwise, the remote plugin will receive *no* key codes at all!

Try to enable debugging in DVB/driver/av7110/Makefile by adding 
"av7110_ir_debug=1" to the "insmod dvb-ttpci.o" line.
By observing debug output you will notice, if you got the correct 
protocol and inversion settings, even if the keymap is wrong.

Once you have found a valid protocol/inversion setting, it should be 
easy the construct a keymap from scratch using the debug output.

It should be no problem to use the receiver with different codes.
You just have to build your own keymap...
