hi i hope someone can help me out im having this issue but it works fine in another room. except when i plug it into my room the box starts freezing on hd channels like movies hd and sports hd. they start playing up. I know theirs nothing wrong with the box and my cable tuner as it works fine in another room all channels and hd channels. Also i thought it could be the wiring so i rewired the whole room thinking it could be the cable but its not and checked all the f connectors and put new ones on them and also have put splitter thinking it could be that changed it over and checked all f connectors on them and still its the same. i hope someone can help me out or give me an idea on what could be causing this freezing on my extrend et8500 on virgin. And also my n line is also fine and put in correctly.
