XMBC Video Stutters on High Res Movie Files Help!

post #1 of 5
Thread Starter 
Hello All-

So my XMBC does play the majority of Blue Ray and HD Downloads with no issue... however it does seem when I download a large Movie (IE 20GB) for some reason on playback it is barley playable... Video barley creeping along and stuttering. Any suggestions or advice how I may be able to fix this?

The CPU is an I7 860 MOBO P55 G55 MSI Raid 5 (14TB) 8 GB Ram.

Is this in issue with the CPU not being able to transcode the data properly? I'm a Noob so not too sure what the problem may be.

Thanks for any help!

Could be the hdd not keeping up. Try the same file with K-Lite Media player classic and see if it lags then.

In my opinion the best media player out there, and can run HD files on even low end specs, unlike VLC.

Got no experience with XBMC though, so can't help you with that.

Often times when we have issues with video playback in xbmc, its not really the video is the cause of the problem, more so its your audio settings. I have found trying to play large files with audio set to hdmi causes stuttery playback. Try changing to analog and see if that fixes the problem. Actually, first you should try playing the file in some other video player like vlc, or k-lite media player as suggested by "go4life". If it plays fine there, then make the audio change in xbmc.

What's your GPU as this will have more of an effect than the CPU for HD playback.

Personally I don't think RAIDs are worth it for domestic use, but that's just me - the data isn't really that critical and the headaches I've experienced far outweigh the benefits. But each to ones own and with a 14TB RAID, you're stuck with it now unless you want to lose it all (another reason I don't like them).

To diagnose your hardware outwith any windows issues, XBMC is cross platform so you could try it on a Linux distro. However you could easily spend longer trying to get it to work in that than sorting your issue!

Any GPU with hardware h264 decoding should be able to handle playback of 20GB 1080p movies. My Raspberry Pi can do that and it's all down to the hardware decoding chip.

My HTPC sounds similar to yours - it's an i7-920. Previously it had a GT240 and would play anything.
