I suspect that the PVR150 receiver can only accept the PVR150 remote (I 
think I recall something about only accepting RC-5) and that you need 
some other way to record the codes from the kreatel remote.
Are you able to use/buy/borrow/build another receiver, i.e. an MCE 
usb-receiver or a serial one to check whether you get any info?

I suggest you try it out on a different machine if you are able to as 
that will keep your mythbox stable, if not, make sure you backup 
modprobe.conf (or equivalent) and lirc.conf.
