Running a clean install of xbian 1.0rc2

Been running xbian and dealing with this little issue for a while... it's not a show stopper but it'd be cool to figure it out.

all my movies are on an smb share over gigabit Ethernet.

I get occasional stutters in predicable spots in movies. I suspect intense graphics are a cause..

But when running top, I see that mmcqd\0 is consuming the highest CPU percentage when it's normally quiet and low on the top list. xbmc.bin is normally consuming 30-40 percent cpu... mmcqd/0 spikes, video stutters... then it resumes and xbmc.bin is top.

thanks all!!!

I would have a look at the load on the smb share first - especially if it a NAS or low powered machine.

Also the RPI is only 100/10!!!

Are these large HD files? If so, can you play them if you copy them to a USB flash drive?

My guess is the amount of data being passed and having to be decoded.

Install nmon - "sudo apt-get install nmon" and monitor the cpu/wait and net traffic. You should be able to determine the area of issue from that (or use top, vmstat)
