I used my old mx-500 to train a bunch of ir codes to my new 980. The new 980 is using a mrf350 with a ir blaster cable connected to a USB UIRT. It seems to work ok, but it is not very smooth. For instance if I press a bunch of buttons fast it does not work well. If I press a button wait a second and press another button it works fine. I can take my old mx500 and click the buttons fast and it works fine. I have tried adjusting the ir power and it does not seem to have any effect. Any ideas? Chad
