Another datapoint from me. I setup a Fedora 10 box with Myth trunk
running alongside my "production" system. For me, using the "Gray" OSD theme, the
OSD works EXCEPT the menu that (can) pop up when exiting a
recording--which is all white. I've since turned that menu off. The OSD
menu and OSD info is readable, provided it isn't displayed over a white
part of the show. I'm still on r19179, BTW, on a Core 2 Duo 2.13 with a
GeForce 9400 GT (512MB).

I was only running with a HD-PVR for most of my test Sunday, but I have a
recently acquired HDHomerun that wasn't setup in the main system yet, so I
set it up on the trunk system with OTA. I did watch a little of the
content from it (MPEG2 HD), but it did look "hard-to-describe" weird.
After the beautiful HD-PVR recordings, it bothered me enough that I go
switch back to a playback profile that uses Xv before I watch those OTA
recordings and only use the VDPAU one for HD-PVR stuff.

I must say, that *IF* you are willing to commit to ALL the requirements of
running trunk (subscribe AND pay attention to -dev and -commits),
understand how to use subversion and compile packages for your distro, learn how to
properly report bugs, etc., THEN and only THEN I say that Trunk seems
very usable for HD-PVR systems--again taking into account the current issues
mentioned above.
