I've tried with LAN instead wifi : better performance, the intermittent stream continues, but with less frequency.
After that, I've tried to upgrade the firmware router and I've set the router to give priority to the video stream (there is a specific option in the asus router) : a bit better, but not sufficient.
All the test was made with no internet access programs running (I stopped emule, panda cloud, etc.).
I'm not satisfied, any other idea ?
Some configuration in the ME samba client ? I'll search some infos with google....
Sell the ME and buy a good, old, XBOX ? :-)
Thanks again
