[mythtv-users] Analog tuner picture grainy

[Steve V]

I think I have found the reason for my grainy picture. It seems to be some sort of interference in the current location of my backend computer. Moving everything to another location in the house improved things to almost DVD quality.

Now I just need to figure out what is causing the interference and I can put the backend back where it should be. I did think it was the PC itself but moving the PC cured the issue so I assume the problem is with the location.

I could try reducing the signal but I don't think that is the problem as the grainy appearance is also on the composite input so its not related to the aerial signal strength.
 
I read up some more and I found that increasing the resolution from 480 x 576 (PAL) to 720 x 576 can improve the picture. I tried that last night and it did improve it but not quite to where i would expect the composite input to be.
 
Now that I have improved the resolution I will go change to the Pixelview card and try the S-Video input (once I get an S-Video cable).

Try reducing the signal strength. I have improved the quality of my PVR500 picture by adding a splitter, and connecting to the 6dB output.
