This was with a brand new AMD 635, with an ATI onboard graphics card hooked to a monitor through a DVI interface, running a fully updated MythBuntu, using an HD-PVR. And this was using the "CPU+" or "CPU++" profile. When I changed the profile to "High Quality" the split screen problem went away but the green band continues. I don't know if the two problems are related.

Setting the deinterlacer to "None" makes no difference... same with forcing video scan to progressive.. the green line is still preset. I haven't touched the HD-PVR firmware, so I could look updating that (I'd have to find someone with a Windows machine)...
