decided to launch xbmc (logged out) on the laptop, connected via cable so settings were intact.
The video does indeed not play smooth at all, it speed fluctuates,
last week i tried an 1080p MKV rip (VC1 inside the container) with lossless audio to my laptop from my desktop pc (both on ethernet) it worked fine in VLC and movie-player today it doesnt

so im not sure its specifically xbmc? nothing else has changed on my setup
how annoying ! i really dont want to have to use windows side by side with linux and its not too slick to have a grub boot menu between openelec / mint on a home theatre system, still it might be the easier option. I think i will try xbmcbuntu and try getting the login bit sorted so on exit to desktop not ideal and not what i actually wanted to do (i like mint sob

)
it just seems to get a converged media,internet gaming setup there isn't anything that works too slick on the market (including games consoles or liveboxs, appletv) as i said being able to workspace between XBMC/ STEAM (logged in with invites and friend chat) / Browser / system workspace is out of the question until
a. XBMC can stream/play properly in mint
b. Cinnamon or someother tool is able to allow for XBMC to be switched whilst inside the application to workspace view
c. Audio issues around lossless are sorted
d. Steam is on linux
is it too much to ask, i feel like all of those above should be readily possible but actually making it work seems to be about just a few small tweaks to software
*edit copying file to laptops desktop going to take a while 16.6gb file hehe (smallest BD rip i have) but the rate is 8.9MB per sec over 100mb ethernet so easily enough transfer for streaming, still i shall test it ,perhaps the last movie i tried wasnt VC1 perhaps H264 but then again thats why they are in containers.
from the original request i still would like the option to choose between desktop launch and logout launch as my laptop is logging out even though i followed the same steps as the desktop.. needs to be clearer for users
