HDMI of tv detects it on hdmi 2 cause tv brief popup changes from 1080i hdmi 1 to 720i on hdmi 2. Ethernet flashing back of box. Picture is scrambled diagonal lines. Pulled ethernet, turned off/on to let use Wifi. Same. Haven't seem any posts yet of scrambled picture. Some said black screen on 1 tv but other tv in house fine. So seems some tvs have issues with it ? My tv is a DYNEX 32" LCD 720p model DX-32L220A12 . Inexpensive model. Maybe that be the prob ? Or cable tv net router provider somehow not allowing such device a clean signal ? Doubtful since a pc has been used to stream from similar sites. This box was loaned to me just to try. Older 1 gb version. He tested it at home. He thinks it may need reprograming. I'm wondering if it's a matter of allowable device, like when past troubleshooting pc net access, noticed ethernet card properties needs to get acceptance from net server showing as 'lease obtained' , etc. ? Maybe like Facebook has security settings as to recognized allowed devices ? Maybe with this box not looking like 1 of my pcs or wifi android cell, it's being rejected ? I kinda doubt it since the light at back of box indicating ethernet traffic, flashes. Seems mostly something to do with tv accepting the 720i and preset box refresh rate. I don't see anything in tv screen menu settings that would effect this. Ideas ?
