on what platform did you try? Can you specify your system?

I tested on an Asus EEEBOX EB1501P which has an atom D525, 2gb memory and an ION2. I'm running ubuntu 10.04. The "new" issues that I experienced were a heavier kind of stutter that looked like it was "trying to synchronize audio/video" if you get what I mean
And the 'old' frame missing was still apparent.
Edit: I think bobo1on1 mentioned a while ago that your implementation of vdpau_interop doesn't do any difference performance-wise.
Edit2: and yes i'm running latest libvdpau, latest nvidia driver, composite turned off, noflip on, etc
with what content, 1080p24, 1080i50 ..., do you have your frame drops?
i am confused: "noflip on", flipping is something you want to be enabled.
have you compiled the patch with glew-1.5.5 or higher?

uh yeah, i mean noflip=false. I've missed the glew part entirely though, gonna retry with that.
The content was 720p24 and 1080p24
ok i installed glew-1.5.8, recompiled xbmc and tried again. still missing frames, and still lots of additional stutter (which doesnt cause frame misses/drops) due to your patch(es).
I have this same problem too. The script in the other thread worked for me in that my set now switches to 24Hz when watching movies, but I have occasional "hiccups". When I press 'o' while the movie is playing, its one single dropped frame, maybe once every 30 seconds or so. Its not a deal breaker, but still annoying.
My setup is a custom built HTPC running Ubuntu 10.10 using a Gigabyte Socket 775 motherboard, an Intel Celeron E1400 2.0GHz dual core CPU underclocked to 1.6GHz (I've tried going back to 2.0GHz and noticed no difference), 2GB RAM running at 800MHz, a Nvidia GeForce 210 PCIExpress graphics card, and a Western Digital green HD. All of my media is stored on a remote Windows Home Server connected through a wired Gigabit connection. My TV is a Sony Bravia 55EX710 TV connected through HDMI.
Again, the script fixed the constant jitter I was experiencing at 60Hz, now I just have an occasional dropped frame about once every 30 seconds.
are your boards equipped with pairs of memory modules to get dual channel? this is a small investment but a huge performance gain.
another idea is to configure ubuntu's cpu scaling to keep the freq. above 1.8Ghz (or so, depends on the system). i have also set the threshold from 95% down to 25%.
audio setup might be problem too. last time i forgot to set resample rate to 48000 in advancedsettings.xml (audio over hdmi) which caused stutter. not sure if pulse audio now supports pass through. i have removed it completely and use esound instead.

I can set the playback to run in 2x speed, and still miss about the same frames. I doubt this is a performance related issue.

This is exactly what I'm experiencing (without fernetmenta's patches) It's not "dropped" in the correct sense though, just "missed" according to the codec info osd

I can't see any problems in this video. "missed" means missed vblanks, not lost frames. there's a correction mechanism to handle this in xbmc.

Every missed vblank causes a small stutter that is very noticeable. That's my problem.
ATV1, linux, Xbmc 10.0 Dharma and crystal hd revision 174.
I have tried everything but I have always from 250 to 300 frame drop for film.
It seems that if i start the film, then exit and restart from where i leave the frame drop are less....But it's like beyond God....Mystic....

My feeling is the same, although it's hard to come up with statistics for this unless I watch the same movie several times - which is, of course, very time consuming.

exactly
I had problems with this on my Barebone (AthlonX2 64 3800+, nVIDIA GT210. HDMI -> Onkyo 607 -> LG 50PK350, 1920x1080p24) but after creating custom modelines the frame skipping stopped.
Worth a shot!
how I create coustom modelines with linux on atv. I'm a newbye for Linux.
And what modelines do you create? I put 1920 1080 24p that my pioneer KRP handle.
