Ok so I have Mediaportal V1 running well and have most of my teething problems sorted. I get a great picture most of the time. However, I continue to get intermittent problems with pixelation or blockiness in the picture. What I mean by this is that I get a transient pixelation effect in parts of the picture (seems to mostly around edges). This only happens sometimes - like I can be watching a program for an hour and it is perfect and then it starts happening every 10-20 seconds or so. This happens in both Mediaportal and DVB Viewer so is not application related.
I have read a few older posts where people have put this problem down to the codec or signal levels. If it was codec related you would think it would happen all the time. Also I think I have good signal strength (line of sight to transmitter and good quality cabling). Has anyone been able to verify the cause of this problem?
