[QUOTE="DrMopar, post: 496476, member: 70303"] Hi, thanks for the reply. I need the masthead amp in (digital certified, fully screened, F type), without this the signal is too weak. I have a splitter in circuit but it is a fully screened F type. I've also confirmed I have a good earth connection. I have the latest drivers for the card and there are no amateur radio masts nearby that I'm aware of. I'm using the latest version of CoreAVC with hardware decoding enabled. I've tried it with this turned off too with no change. (Other than my CPU goes from 10% to 30% during playback) Most of the time the signal is good and I have a clean picture, every so often I record something and find brief periodic (maybe 10 - 20 minutes apart) pixellations. They are in the exact same spot in the programme each time I view it with different codec settings enabled leading me to believe at this stage that my issue is record quality rather than playback. I've not been able to reproduce the effect manually leading me to think it's possibly interference. I'm trying to work out a simple way to measure my signal strength so at least I can rule that out but without a signal strength meter of some kind this is proving a bit tricky. :( [/QUOTE]
