Okay, firing up new machine!
MSI 8500GT
2Gig RAM
Asus P5K-E M/B
crap 80gig IDE drive
E6750 C2D @ stock clock - it can be pushed
At desktop: 60FPS, CPU Total is 51%, XBMC is 100% heh - guess one core maxxed? Playing an MKV that previously choked the XBOX I get 24FPS, CPU is 36%, XBMC CPU is 70-74%.
I do not have sound right now, no speakers and stereo inother room - TV hookup is planned ASAP. The board has optical and coax out and I've put the SPID/F onto the vid card so that it will go out via HDMI too - not sure anything special from Linux is needed for that but frankly optical is how the XBOX and other devices are done now so I'm okay with that. We'll see if I have to do anything to get the HDMI working as video out later. Need tofigure out navigation too! lolI call this a success! I will now work on getting Lirc working on this box. I may explore Myth and poke at Linux MCE. If anyone has questions on setup fire away and I'll try to answer. Frankly I'm no Linux pro but can get around in it and I did this following freely available info.

Lirc working pretty easily this time. Indeed the keyboard keys are not mapped. A program named "irw" at console will allow you to see what the keys send that are mapped. I'd love toget full keyboard going but for now knowthat the peanut remote works fine!

hmm... 100% when watching nothing?? that's not normal is it?
was planning on buying a E6750 C2D myself too for building a HTPC.. but hoped the CPU would do a bit better.. the .MKV you tested was 1080p or even 720p?
- BLKMGK - 2007-12-06 22:56
CPU TOTAL was only 51% no both cores. The MKV was a downloaded TV video, HD but might be 720. There was some mention of sample vids earlier but I don't recalla link to any - I'd be happy to try one and report back. UI response is pretty snappy and except for bugs that I'm sure will go away with time it runs perfectly fine. I do need to hook it to speakers or my stereo to make sure sound is keeping up but right now it seems pretty good, no lagging or jitter in video - smooth as silk. The CPU could certainly be overclocked a good bit too if I need the power. The biggest weirdness is when I end a vid the menu returns only smaller like it's windowed down in a corner <shrug> I also cannot figuere out what key would be equal to the white controller button on the XBOX.
IMO this CPU is fine with current codebase, if someone has something they would like me to test to stress it just give me a link here or PM me one - happy to help!

Hmm, still dont get it all.. 'CPU TOTAL' do you mean:
1. Overall usage of the CPU was 51%? and this is when doing nothing, just have XBMC running? (So in this case 1 CPU would be maxed out)
2. Or do you mean only 51% of the Total CPU is available, so 1 core is not being used by XBMC.
Well for the 1080p you can try find an 1080p.mkv on the internet i think the same place as where you get your 720p.mkv tvshows should have some of 1080p too.
Or else try a 1080p trailer at apple.com

1. Please post Your results along with codec (for ex x264 as it is more and more popular), container (for ex. mkv) and finally if it is 720i/720p/1080i/1080p (i or p makes A LOT difference so please don't make a mistake
). Also if vsync is on or off (it also impacts framerate a lot).Maybe it would be a good idea to make a wiki page with configs and results in order to keep it in one place as a little help for ppl wanting to build their own box for as less as possible
2. I also don't get CPU-Total Vs CPU-XBMC

CPU-Total is how much cpu Linux is using all together max 100% no matter how many cores
CPU-XBMC is how much XBMC uses the difference is xbmc one uses 100% for each core of the cpu so its max is 200% on dual core machines

Ok thank you for making that clear..

but i think it's rather strange that in 'idle' on XBMC desktop one core from an E6750 would be maxed out? This doesn't seem right, does it? I thought the only problem would be playing HD-material.. cause OpenGL support would take care of the XBMC-part using HW-acceleration?
Further i think in BLKMGK's post he states that when he's playing an 720p .mkv the CPU usages drops to 70%.. just didn't make any sense to me.. cant see in which way playing an HD-video would make the CPU-usage drop...

Okay, I had some MKV that wouldn't play on my XBOX, I chose a couple of them and tried it on this system, I reported the results. I didn't create these files and thus am not intimately familiar with what was done to create it, judging from the file size of 1gig they are probably 720 but on a 24inch monitor who the heck knows. I do not think I've got a tool that will discern the resolution but am open to using one. As I said previously I'm not a Linux wiz so doing this in Windows would be easiest.
I am also open to testing whatever files folks would like me to test so long as we're not talking HUGE files grabbed from slow servers. I do not have the ability to easily create test files nor am I willing to look all over the place to find specifically encoded test files - point me to what you want me to test. An Apple trailer should be no biggie, I'll hunt up one of those in as high a def as I can find assuming they are not heyuge and play it over my network.
CPU Usage - I didn't write the code, I simply reported the results. It was fairly clear to me but I can see how it might be confusing - the system doesn't appear to strain when the code is run. <shrug>
Downloading the National Treasure Trailer1 1080P file now in .MOV format. We'll see if it flies and I'll report back. I chose this because it interests ME, want another? Suggest it and provide a link if possible.

The best way to do this is for someone to find a bunch of various clips that everyone can download. We could probably find them by googling pretty quick around. I can host a wiki page on one of my servers if we need this. But we need to have tests cases that everyone can use and report back , instead of various different clips.
anyhow im game on helping out.
