I bought a HDMI cable from Verizon yesterday. I was able to connect it to the TV at work and it played with no problems. Its a Vizio. Today I tried to play it on my Samsung and it won't play. Sometimes the audio will play and the picture is just froze or stops and starts. Then it will sometimes says error playing the video file. I tried changing the settings on the HDMI output and I tried changing the screen formats on my TV. Any ideas?
