[mythtv-users] How can I change channels on a Cisco HD271 DTA (with TWC)?

I was wondering if anyone got an ir blaster to work with the dta271.  I
tried the MotorolaDTA100-PaceDC50X remote entry and I see the blaster blink
when it is sending entries but the dta271 does not change channels.  I was
just about to try the RNG-150  entry but noticed that it is essentially
identical.

I'm using the blaster on an pinnacle usb mce.

Any help changing channels on this item would be gratefully appreciated.

Thanks,
Tim
