[mythtv-users] Ghost image on my PVR-350

[denis-carl robidoux]

In my case the "ghosting" is a constant element.

It does vary depending on the brightness and complexity of the background
wall but it doesn't matter if I'm on LiveTV, high quality or low quality and
getting in and out doesn't change a thing...
