Ok so I recently upgraded from a component cable to an hdmi cable on my xbox 360 and i am currently using an vizio lcd hdtv. I was amazed when I first saw the quality of the hdmi cord but when I booted up a game I disconnected from xbox live and messanger. When I rejoined xbox live I joined a chat but I could barely hear the person I was talking to because its was so choppy. Then while I was playing a game the screen froze but music in the backround was still playing and I could even open up my guide. But after browsing through my freinds list my xbox completely froze and I had to restart it. This has happened many times now and I have even tryed to lower the quality from 1080p to 720p but that didnt work. This never used to happen when i was using a component cable. Plz HELP ME FIX THIS!!! Im using an original xbox btw.
