I have the blackhole 179 image on my duo and works fine
make sure you check fta channels if checking for freezing as a bad "aquatic-mammal" will give freezing and glitching issues, so check you can see ecm times by pressing OK twice in rapid succession and the onscreen banner should report the ecm time to you, needs to be low and the lower the better but you cannot improve it so if its bad coming in it will report it as high level and glitching will occur
