[mythtv-users] IR Blaster Inconsistencies With Recordings Only

I had a similar problem when using a basic IR blaster to transmit to 
a Dish 3100 STB.

The Dish receivers expect a higher-than-normal 56 KHz carrier 
frequency. If the PC is doing anything at all 
computationally-intensive, that 56 KHz can be a little slower at 
times, and the receiver misses digits.

The solution is to get a blaster which generates its own carrier 
signal, rather than relying on LIRC to generate it in software. I got 
a USB_UIRT2, but others work as well.
