I just got a second-hand (couple of months old) HD-EP10 today, upgraded the firmware so it's region free and whatnot and things seem to be working fine. However, something really strange happens once in a while. When inserting a SD-DVD upon watching a HD-DVD the machine screws up. The picture either gets really pixelated or starts 'blinking'. If I turn the player off and on, the disc works fine. I don't know why but I think it may have something to do with 1080p upscaling as it seems to work fine with 1080i. I've tried two different HDMI cables but that didn't make a difference. Has anyone else experienced this and knows what I'm talking about? My tv is a spanking new Panasonic 37LZD85
