I am completely frustrated with trying to get HDTV working. I can get
720p (with issues) but not 1080i. I've tried different drivers, cards
(both Nvidia PCIE), modelines, and both DVI and component video.
Setup
-----
Nvidia Geforce 6600 (DVI and component out)
Fedora core 4 x86_64, up to date
Nvidia driver (tried last three, including very recent patch)
Athlon-64x2 3800+
1GB RAM
Mitsubishi WD-52628 TV (internally 1920x1080p)
Custom built 2.6.15 kernel, though Fedora kernel doesn't work any better
The TV accepts 720p and 1080i via component and HDMI. Both inputs
worked fine with an upscaling DVD player (720p and 1080i) and the cable
set top box (1080i).
I really want to do 1080i, since the cable source material is all 1080i
and the TV has 1080 lines.
Here's where I can do.
1. With special Modeline (I've tried several) I can do 1080i and get a
really nice desktop (component only). I can bring up mythfrontend, but
if I try to play video (NTSC), X goes crazy. X takes 99% of one core.
I have to ssh into the machine and shut it down (everything, not just X)
to get decent video again. Running mplayer does the same thing, whether
given 1920x1080 or DVD material or NTSC-based .nuvs.
2. With the special modeline I can do 1080i DVI->HDMI, but the
interlacing is off by several millimeters. Several people have reported
this.
3. I have been unable to get 720p to HDMI working.
4. 720p to component video presents a lovely desktop and video plays
(high def and NTSC, including mythfrontend playing NTSC). I don't
specify any special modelines, but just tell it to use TV "HD720p". The
high def video (mplayer) looks decent enough (though 1080 would be
better), but the NTSC from myth looks like crap. No matter what
deinterlacing method I try the playback looks lousy whenever there is
motion.
I haven't even bothered with the highdef backend (I'm just connected
over the network to the existing NTSC backend). There seems little
point in capture stuff I can't view. Sample 1920x1080i files were
captured a couple of weeks ago when I was playing with the HD5000 card.
If anyone has 1080i working I'd very much like to see your xorg.conf and
know what card and driver you're using.
If I ever do get this working, I'll post a complete report.
Thanks for any help.
