Sorry too, this is the last OT on this, just to answer your question: The scraper not always defaulted the "best" covers and fanarts. It means I actually change them at least in case of half of my movies.

motd2k, I just wanted you to know how grateful I am for vdpau. This has been the single best 'selling' point I make when getting friends to make the conversion to XBMC.

Haggy Wrote:Other than that - you do know that it has been fixed in linuxport, so why not switch there or at least patch it in for yourself?
I am running the LINUX port and the problem is still there.
What I am saying this problem started in the vdpau branch sometime after 18158r and was still there even after the change logs for the vdpau branch stated that hanging was fixed.
And I am sure this bug was merged with the linuxport as well because I am still seeing the issue in the linuxport version as at this morning's update.
It is actually network playback of VOB files that are the issue. AVI and .ts are fine and stop and return to the library.

I am not having this problem (I don't think, maybe I always hit stop) - but my CPU is staying at 100% after playing back a DVD ISO over the network. I will investigate further later.

Ah now i get it, sorry. Always thought you stayed in xbmc-vdpau. Did you open a trac ticket?

Just got this compiled and installed. Had to wait for a MSI NX8400GS 512 MB to come in, but now that I've got that and this working. It was well worth the wait.
Now my cpu usage is barely above 5% per core, average is 1-2% per core. I got an AMD Athlon x64 4600+ cpu. It even works with movies I had encoded before at the maximum 5.1 level.
The only problem I'm encountering is that 24p movies aren't totally smooth on my 1920x1080i60 HDTV and it doesn't support a 24 Hz refresh rate.
Jerky, suttering playback with 24p movies - noeikujoo - 2009-03-25 12:47
This is my first post to this forum. Sorry for my bad english...
I am running XBMC VDPAU 18735 revision in Ubuntu 8.10 2.6.27-14-generic and the problem is that 24p (23.976 fps MKV's) movies aren't smooth. I am using XBMC's auto refresh property and I have a Full HD projector, whitch supports 24Hz, 50Hz and 60Hz refresh rates at 1920x1080 resolution. I am using Nvidia 185.13 beta drivers.
When I am watching 24p movies, CPU usage is only 2-4% per core, but the movement is not smooth. My 1080p MKV's occasionally judder and it is very annoying. The movement can be smooth for minute (or two), but sometimes playback slows down for short time. It looks like that movie jumps suddenly forward one or two frames. XBMC's info shows that frames aren't dropping.
When playback judders, XBMC info shows that frame rate varies between 23-25 fps. 25 fps and 29.997 fps movies playback is fine and XBMC's info shows that frame rate is stable.
I checked from projectors menu that resolution is 1920x1080@24Hz with 24p movies. I got an Intel E6600 C2D dual core prosessor and PALIT GF 8400 GS PCIE 512M DDR2 DVI HDMI VGA-card.
Without VDPAU support my processor has not enough power to play smoothly 1080p h.264 29.997 fps content.

noeikujoo: I second that. For me, playing back some files (especially the killasample) is even bader. I also get the experience of the movie 'jumping' back and forth to keep sync with the audio. this only happens on vdpau.
one question: are you on x86_64 or 32bit?

I did not open a Trac. I have done a debug log, but it still shows nothing about the problem. It is still there in Linuxport 18910 as of yesterday.
I guess I'll have to revert back to the 18158 vdpau build.
I tried everything to see if it was my system. I got rid of my .asoundrc, advancedsettings.xml. Changed from hdmi audio to spdif again but the problem is still around.

I agree that juddering is badder for some files, but all 24p clips that I have been tested stutters at some point on vdpau.
