Hi Ghost,
The problems with hdmi connection losses occur by me with the drivers of 05102009. At that moment i was using your CVS image.
As a test i installed an image on my DM800 developped by a dutch image builder. At that moment i had with the same drivers no hdmi connection losses. Then for the test i changed the kernel of the dutch imagebuilder with those of the DMM CVS and after 10 minutes i had hdmi connection losses every 10-15 minutes. So changing the kernel hdmi connection losses were reproducable. So i think that you have also to look at the CVS kernel. At the moment i use the image of the dutch imagebuilder with the latest dvb drivers and have no HDMI connection losses.
with regards, Jan
