Have you tried the open-source video drivers. They are much
improved since EL 5. The mythtv box is using the radeon chip on
the motherboard:
01:05.0 VGA compatible controller: ATI Technologies Inc RS880
[Radeon HD 4200]
01:05.1 Audio device: ATI Technologies Inc RS880 HDMI Audio
[Radeon HD 4200 Series]
I also have a Fedora laptop using the nouveau driver and
mythfrontend runs fine on it.
The laptop also has 4 defunct mythfrontend processes, but it has the
RPM Fusion build of mythtv. This might be an upstream problem.

What's your video output like? I haven't revisited the whole video
support issue in a long time. I settled on Nvidia + VDPAU quite a
while ago. I need to drive Full 1080 HD on a 60" plasma and don't
have room for any hiccups.
The CentOS 6.2 box is driving a 720p TV via a DVI/HDMI connection. The
Fedora laptop is a ThinkPad T61 with a 1440x900 display. The source
material is mostly 720p and 1080i ATSC off-the-air. Playback is smooth
with both systems. (I did see some stuttering with CentOS 6.0, but
that's been resolved.) I was pleasantly surprised that the motherboard
video card with the default drivers produced watchable video and
digital audio. That had never happened before with Linux. I had even
budgeted for a discrete video card which I ended up not buying.
My previous MythTV box ran CentOS 5, and I used the Nvidia drivers on
it, because the default drivers weren't good enough.
Also, at $dayjob, I have a Fedora workstation with a 1920x1280 display
and the nouveau drivers work well with it, although I don't do much
video.
Your results will depend on your exact hardware, but situation is
better than it's ever been before.
I've just installed mythfrontend on another CentOS 6.2 X86_64 box (don't
know why I didn't think of doing this before). It has on-board Radeon
video (so no Nvidia driver) and after playing around watching some
livetv & recordings, no zombies.
It looks to me like it could be the Nvidia driver. I'm going to give the
Nouveau driver a try on my main mythbox but I don't know how it will go
with a fairly low-end CPU (AMD dual core 4850e).
Steve.
