Whenever I try to connect to Xbox live using my HDMI cable, I can never seem to stay online for more than a few seconds or so until it constantly disconnects. Everytime I try to play a game singleplayer or multiplayer it instantly disconnects yet again. When, however, I switch to my deafult AV cables, My xbox connnects and stays online with no problem and I can play online with no dissconection or lag. So, I was wondering if anyone else is having this problem or if anyone would like to shed light on solving this frustrating annoyance. Thanks.
