have you tried the new fake HDHR that was created for a bunch of different sources? there's one for pluto:
i'm planning to give it a shot at some point, but i just haven't gotten to it yet. i am using the locast implementation though to get locast into channels with the correct OTA channel numbers, and it has been working very well. some minor issues that i've worked out with the dev over the past week, he's very responsive on github.
