I'm helping my brother set up his first MythTV installation. He has an old, slightly upgraded Dell 8200 with a pvr150 and an FX5200. He is capturing video from a STB via co-ax. While the picture looks fine when routed to the TV, when routed to the pvr150, portions of the image are often mis-aligned and jump all over the place. I don't think it's ghosting and I'm not sure if there is a name for this, but I've put a small sample on this webspace temporally to better show what's going on. If someone wants to host this more permanently, please do, it's ~3MB.

He seems to notice a correlation between the time when the graphics go away (such as a replay) and when the image stabilizes. The distortion is worse (more common) on some channels than on others--but that could be due to the previous phenomenon and the type of content typical to various channels. Remember, this is an STB feed and the pvr150 is not changing channels.
