I just ripped my Star Wars BR disk, and to my surprise cannot play it on my Ion (Atom 330) based system. See my sig for details about my setup, but it's a pretty straightforward first gen Ion with the dual core Atom, 2GB RAM, Dharma Live.
The issue is extreme jerkiness, which looks like is caused by dropped frames. The file I am using is the opening "crawl" from the movie, I think it's called 000302.m2ts and it's about 750MB. Same problem on the 40GB main movie file, but this one was easier to test with.
The context menu shows all 4 cpu cores at less than 10% load, vdpau enabled and frames dropping mostly when the bandwidth gets to 35Mbps or so. By the way, what is the "pc" number at the end of that line?
I was accessing the files over a 100Mb network via SMB, which I thought might be the issue. So I switched over to NFS, which did improve things in that there were less frame drops - but it's still unwatchable. Next I copied the 750MB file to the local disk in the xbmc machine - an Intel SSD. To my surprise, it still drops frames and is unwatchable. I'm interpreting that to mean that this is not a network bandwidth issue.
Is the Ion not capable of 40Mbps playback? I would be shocked if that were the case.
I have read a bit about big improvements to libvdpau recently - but I don't really want to experiment too much with my "production" box. I like to keep it on the official releases since the wife wouldn't be happy if I left it in an unusable state.
Anyone have any idea? Anyone with a similar setup that could try it out?
