It is more likely that the problem is within the or51132 frontend driver, rather than in cx88-dvb, as this was the case with lgdt3302. Maybe the problem in lgdt3302 came from the original or51132 design? Any ideas Mac? Maybe the same type of fix can be applied? I have cc'd Kirk Lapray, or51132 author. -- Michael Krufky
