UPDATED to add comments on intel and nvidia video issues. See bottom of this post
That said, here is what I went through.
restore backed up udev rules for video devices into /etc/udev/rules.d/*
I am running into a problem with the latest version of the intel video driver for intel integrated chipset I am using - H55 With a Clarkdale i5 processor.
Actually I think it is my Onkyo AVR thinking the HDMI signal is analog and not rgb.
Before I upgraded to F17 (from F13) things were okay, but now when the signal is processed by the AVR my screen has a pink shade to it.
When I bypass the AVR and go straight to my TV everything is fine.
So I need to figure out if I can force some setting in the driver to be a certain signal to get it to work.
I went out and bought an NVidia based card (they are cheap and I know they have good VDPAU suppport). I'll let you know how it works out.
Seems the Onboard Intel video does not like/allow a 2nd video card. When the bios has the intel onboard starting, the nvidia does not work. Hmmmm, Fedora sees the card but won't work. Driver install from source does work.
Interesting side benefit since installing the nVidia driver (even though it does not get loaded) is that the colour issues on the Intel output is fixed. (nice, but I do not know why)
I am finding that my Intel integrated video (Intel H55 chipset on my Asus P7H55-M Pro motherboard) is not up to the challenge. 1080 HD h264 video has a very slight but noticeable stutter vibration. I went through pretty much every MythTV video playback setting and DE-interlace setting and nothing helped.
Finally I had some success when tried disabling composite in the X configuration. This disables the use of Gnome 3 but that's fine since this is a dedicated MythTV box. I still have visible DE-interlace lines that the Hardware can't seem to get rid of.
I have spent hours on config settings :(
Trial and error found a de-interlace setting that gives me a visibly usable system!
Everything now seems to be working without any visible glitches!!!
