Your timing is pretty good. Last week I tested sd playback with no
problems. Yesterday I got some hd recorded from my dev myth 23 backend,
and tomorrow I should be testing the playback of it.

Just a 10.04/.23 status update. I've configured X and mythfrontend on
my xubuntu 10.04 atv install. Bootup memory usage is under 230MB, with
no swap being used. I have not tried playing any videos or recorded
shows yet.
This is a bit more memory usage than I had with 9.04 and myth .21,
that combo used just under 200MB after bootup. I have not seen if the
new mythui can be made slimmer yet.

Robert,
A couple years ago, with the help of Scott and this site, I got my
appleTV to run MythTV on MythBuntu 7.10. Everything was great.
When Ubuntu 10.04 rolled around I figured it was time to update my
server which includes my MythTV backend, and assumed that I'd just
upgrade my appleTV to 10.04 as well so the frontend would still be
compatible.
I had trouble with the upgrades so I did a fresh install of MythBuntu
10.04. I've been told and have seen trouble with the memory footprint
of 10.04, but I haven't started working on that problem, because I
can't get smooth playback.
When I use XV I get a stutter every 5 seconds or so and the CPU is
pinned, as is expected. When I use XVMC, and it seems to be using it,
I get a constant stutter, 15 times or so a second, and the CPU is
pinned.
I'm curious if anyone has been successful in installing MythBuntu
10.04. I'm fine starting over and reinstalling, but I'm afraid I'll
end up in the same place. If people have had success upgrading to
10.04, then I'm fine installing an older version, getting it running,
and then upgrading.
Thanks.

Phil,
Thanks for the reply. I'll check on the version of the nvidia graphics
driver, but it was the default that came with Mythbuntu 10.04. I am
playing US OTA recordings, 1080i and 720p mpeg2. Before I made the
fresh install of 10.04 I had no problems with Mythbutnu 7.10 playing
these same recordings.
Thanks,
Dave

what version of nvidia graphics driver are you using?
what type of video are you playing? h.264?

So after a reboot (previously done countless times) XvMC appears to be
working and there is no mention of VDPAU. But the video playback is
worse than ever. There is a constant stream of "NVP prebuffering
error"s and the CPU is still maxed out.
I doubt that it is related but the underclocking won't stick. I can
even run the script manually, or even manually enter the nvidia-
settings commands from the command line. There are no errors but also
no results. Only after going into the nvidia-settings GUI and making
the change does the clock actually change.
Any thoughts? Paul, did you have any problems playing back HD? Has
anyone gotten this set up to work?
Thanks.

I've followed every mythTV/appleTV/XvMC guide that I could find but it
appears that I am not getting XvMC to work. My log says

instead.
I had another error complaining about not finding the XvMCConfig file
since it was in /etc/X11 instead of /etc but I fixed that. Everything
else seems to be configured correctly, but it just won't work. Why is
it trying to use VDPAU? Is there anyway to disable this? Could this be
what is thwarting XvMC?
Thanks in advance!

I need to correct my earlier post. I was testing an SD program that
was recorded on an HD channel. When testing true SD, mythfrontend is
only taking ~30% of the CPU. When decoding HD the CPU is pinned.
I'd love any advice that I can get.

I was running Mythbuntu 8.04 on my appleTV for a couple years and had
to upgrade when I upgraded my server to 10.04. I just assumed that
installing a fresh copy of Mythbuntu 10.04 would be the smart thing to
do. Maybe I should have researched a little more.
The install went fairly smoothly, it is up and running and
communicating with the server. Both HD and SD content plays well
except a blip every 5 seconds or so. I figured it had to do with the
gpu clocking. I can't seem to set the speed through the command line
or in a script, but it does work using the nvidia-settings GUI, but
even then the blips continue.
I have seen a lot of swapping, but I was hoping that was because I was
running other programs as well (terminal, nvidia-settings) and
normally I would only be running the front end.
Does anyone have suggestions on how to "slim" it down? Or should I
just jump to 9.04 or 9.10?
Thanks!
