Hi, I have a DVR system by avermedia (eb1304net) and iphone 3gs. Downloaded I-viewer from appstore and set it all up and it worked until a few weeks ago. Now every time I try logging in from iphone or win xp, explorer I get the message "starting network failed!" but the correct number of buttons light up. Checked network settings in the dvr but no change needed! Any help is appreciated. Gary
