Waiting on dev build 6.3.004.013 - the 011 and 012 builds did not work for me as there was a bug in menu.py which surfaced in my sorted menu. I did run the 012 build for a couple of days unattended on my single tuner HD61and the scheduled run of OpenTVzapper worked fine, but I didn't try to provoke the huffman error. Once 013 is available I will download later tonight on my Quad Plus and test.
