irrecord not reading IR signal on Echostar 5.3 148785

[Identify T. <ide...@gm...>]

I have two remotes that work with irrecord and a third that won't  
record. The remote is an Echostar 5.3 148785

For some reason it's not picking up the IR signal of some buttons. But  
here is what is strange. If I press the button rapidly it will start  
picking it up.

I'm not sure what's happening. Also mode2 reads every button fine.

Any ideas?
