Bought the PVR last week and immediately had issues with recording and viewing. Normal viewing whilst not recording is good 100% quality and 80+% signal strength. Problems begin as soon as I start recording and change channels, the picture starts freezing every second and the audio stutters, sometimes the other channels say no signal during recording. The quality strength goes from 10% - 100% every couple of seconds and the signal strength stays at 80+%. The quality of the recording also suffers and is barely watchable caused simply by flicking channels. Is there something I can do (tried resetting) or do i send it back to Currys. Any help much appreciated!
