--- Comment #5 from Daniel Drake <dan at reactivated.net> ---
You're right, it does seem to work OK against an actual TV.

Really strange because I tested against 2 PC screens, one from Dell and one
from LG, both offer 1080i in the EDID and suggest that 1080i is supported in
the spec sheet; they say "1080i" in the OSD when that mode is selected, but
wobble horribly.

I also tested both displays against a laptop with AMD graphics, both under
Linux and Windows. In all cases the wobble is there too. So as strange as it
is, this would appear to be a problem with the displays themselves.
