I had a similar problem with my MythBox... however I don't know if the
situation is similar.
My box was able to view live TV after doing the initial run of
mythbackend and frontend run as the *user*, however when I set
everything up to startup automatically, I would get the same two-second
error with LiveTV.
Tore my hair out... and so two things have come out of it.
1) I'm bald.
2) Even better, I found a solution.
What I ended up doing was actually starting mythbackend and mythfrontend
as the user who was going to access the system (mythuser in my case),
and I no longer loss LiveTV ability.
The socket problem *I believe* is related to the fact that the system is
attempting to access the capture device and does not have accesss to it.
As far as I know, solutions to this would be to run mythfrontend as SUID
root or to run the frontend/backed as the user. I don't know if this is
a catchall, but try it out and let me know if it works for you. Good luck!

Hello,
I feel that I'm almost there. I have finally got a live TV picture on
the screen. Alas, it only lasts for a couple of seconds, then it
freezes and after a while I'm back in the main menu.
I'm running MythTV on an AMD64 configured as an Athlon-XP. However, I
have configured the kernel to use frequency stepping with the new
'conservative' driver, in the Power Management Options -> CPU Frequency
Scaling. Here's an excerpt from the kernel documentation
(v2.6.12-gentoo-r6):
# 'conservative' - this driver is rather similar to the 'ondemand'
# governor both in its source code and its purpose, the difference is
# its optimisation for better suitability in a battery powered
# environment. The frequency is gracefully increased and decreased
# rather than jumping to 100% when speed is required.
# If you have a desktop machine then you should really be considering
# the 'ondemand' governor instead, however if you are using a laptop,
# PDA or even an AMD64 based computer (due to the unacceptable
# step-by-step latency issues between the minimum and maximum frequency
# transitions in the CPU) you will probably want to use this governor.
The beauty of this driver approach is of course that the box is _very_
quiet when not working. I'm not quite sure if this is directly related
to my problem, because I can force the CPU to spin up with another
program, like setting mencoder to transcode a file for about a minute,
press Ctrl-C, and immediately start "Watch TV" in Myth. This makes no
difference at all.
Below is a terminal dump from mythfrontend. I haven't bothered getting

I live in Norway, a PAL country, and have altered the Live TV output
format to 720x576 per the instructions at
<url:http://gentoo-wiki.com/HOWTO_Setup_MythTV>. That doesn't help
either. Any hints?
