Don't know if its related, but if I connect one of my DM500s to a tv using a Scart lead I get a picture. However, if I then connect another device using the video and audio RCA connectors, I lose the picture on the Scart output.

First thing to do is to make a complaint to your electricity supplier!!

Sorry, cant help you with image problem ,but would strongly recommend you get an electrician in and find the source of your electricity problem...in the meanwhile ,,?possibly reflash with a different version of the image ?? and a fresh search of channels..sorry ,but thats all that occurs to me at the mo..
