OK, so I was watching an HD program (720P @ 24hz) and about 7 minutes in the video went all juttery. This is with the desktop set to 1080p@24hz and XBMC set to adjust display refresh rate based on video. If I press "O" I notice my missed frames keeps increasing ( seems to be common place however).
Ive also noticed that the fps is never a constant number. It keeps fluctuating between high 23 and low 25 fps. Just kind of thinking out loud here but if my fps climbs too much out of the 24fps range, will XBMC attempt to alter the refresh rate? Im going to keep an eye on this and see if I can pin point when the video begins to stutter.
Hmm on a whim I decided to fast forward while the "O" menu was on screen. During fast forwarding HD content, the fps drops to high 19s - low 20s :O .. Is this normal? Im still thinking that my fps are dropping so low (or going too high) for just a split second that XBMC is detecting a refresh rate change, but before XBMC can switch the display accordingly, the fps jump back up to 24 and this is whats causing the juttery playback....Is there any validity in this or am I just crazy?

I have already said this a couple of times in this thread. Vaapi and 24p has some serious problems.
The only workaround I know is to apply the patches from FernetMenta. Search this thread around page 50

OK I'll give that a try. I saw that back there but I wasn't sure if those patches were still relevant. Thanks again.

Well not sure whats going on now but 2 minutes after ( I kept a time log) I either change to tv input or turn off the tv for the night, XBMC freezes and I have to hard reset my machine. This has happened the last 3 or 4 times. Im running CCC 11.11, desktop resolution is 1080p @ 60hz, and I have installed all the FM patches that were available...

After five weeks I got my Zotac Fusion back from the factory after repairs, so I was lurking for the last 20 pages or so. Anything relevant changed?
Is changing repo still recommended?

It's more stable (no crashes the last days), doesn't run out-of-sync anymore after pausing, runs more smooth in general and 24p runs fine now.

The only real error I'm experiencing, when going through XBMC menus, the video playing in the background is jerky, jumping back and forth a frame constantly.
Any splitted-desktop repo yet?
Manual updating is not fon to due.
grolim64 Wrote:getting updates (including a new libva) from ubuntu-x (ppa:ubuntu-x-swat/x-updates)
Should I update at all?
I hear so many problems on these pages, it sounds like I'm lucky to have it working at all.
Xorg.conf compositing, relevant?
tjones Wrote:It turns out the composite disable xorg.conf edit is for better h264 playback. Dropped my cpu usage from 40-50% to ~30%.Does disabling composite actually disable 21st century compositing? (Nice windows in XFCE and stuff), or does it mean something completely different?
Note that I have no xorg.conf at the moment, I sort of like it that way.
Can XBMC idle 24/7 yet?
Leon-B Wrote:I also get a cpu utilization of about 63% when xbmc idles with the latest nightly builds of Eden, so that doesn't seem less so far. However, from the moment on that it blanks the screen, it will have a cpu utilization of ~9%, when playing 720p content, it's around 23%.
Do you mean the 'screensaver' blank or the blank before playback?
I want to have the lowest possible power consumption when not viewing any movie without having to manually quit XBMC each time.
Any hints on mplayer or gstreamer vaapi compilation?
I still cannot compile mplayer or gstreamer with vaapi support which is unfortunate because I don't want to use XBMC as desktop media player too, but if I was on to something last time, I forgot about it.
VLC has built-in support, but performance sucks considerably compared to XBMC.
There's so much handy information in this topic, but topics are generally quickly becoming a monster to search through sanely.

In short, save yourself the headache and buy and NVIDIA based platform...

This is not nice We currently put a lot of effort in better support for this platform. All contributions by the entire community are highly appreciated. I got into contact with the ATI devs and they do care about improving things.

Concerning this excellent guide, I am planning to buy Asus E35M1-I DELUXE too.
Is this guide also viable for an ubuntu minimal installation? (i would like to try it with a ubuntu 11.10 minimal cd) Didn´t Unity give problems with XBMC? Or am I missing something?
Off topic question:
Can you use a HDMI directly to initiate the ubuntu instalation or do you have to start with a screen connected to DVI?

No, I know and I really do appreciate yours and everyone else help. I think XBMC with ATI has come a long way and I appreciate the fact people are trying to get it running. With that being said, at the end of the day I just need something that works. Unfortunately, ATI has just way to many problems right now with Ubuntu. The fact Im totally new to Ubuntu doesn't help things either I'm sure. It seems like an endless circle of fix this, now this doesn't work and so on.
I can't be messing around with a system for a month only to not have it work. I really hope someday this will be a thing of the past, but right now I think its just easier to start with NVIDIA from the get go. Didn't mean to sound unappreciative, I'm just having no luck. I ordered a Zotac ND22 zbox this week and hope to use that until the ATI things gets ironed out.
So basically my advice is if your new to Ubuntu, stick with NVIDIA. If your feeling adventurous and have more patience than Ghandi, then by all means try XBMC+Ubuntu+ATI...
