I am a new to this site so I not sure if this problem has been addressed. I have a Toshiba TDP-S3 and I am trying to run my DVD player through the M1-DA port. I have pruchased a M1 to DVI adapter and hooked up a DVI to HDMI cable from the projector to the DVD player. I get a great picture for about 5 sec and it starts to flash the screen on and off. I have my DVD player set to auto and the same thing, then switched it to 480p and no change. I have tried 5 diffrent DVD players with the same out come. Has anyone had sucess using this projector or an LP500/530 in HDTV ? any thoughts as to what I am doing wrong? All help would be appreciated. Thanks
