How could the OP be getting 4x3 F1 on SpeedHD? Only way I can think of is by pressing the format button ("*") until it was on "Gray Bar", where the receiver would be painting gray bars over the active 16x9 picture. All the other settings (normal, partial zoom, zoom IIRC) should fill the screen.
I'm pretty sure I have some F1 on my DVR, I'll post some captures this evening if they're still on the hard drive.
