Ok, so I have google my mind away trying to figure out what is up with this. I can watch full screen videos to my hearts content on this laptop. However, when I hook it up to my tv via HDMI it will not play the majority of videos full screen, or even not full screen. So, let's start with what it WILL play.
It will play YouTube videos and any videos I have on my portable hard drive. It will play them full screen, no problems. It doesn't matter how long the video is. That is it.
Now, if I try to play any other streaming video, it will play full screen on the laptop, just not on the tv. If I try and watch the SAME video on the TV it will start out fine, but within 5 mins it will start skipping on the video. By skipping I mean, the video will run sluggishly and jerkily. It will freeze and then zoom forward as if trying to catch up to the audio.
This is not my laptop, it is on loan to me. My house was broken into and my laptop was stolen. I never had any problems watching anything on it when it was hooked up to the tv.
I'm not sure what info you need from me about the laptop to help with this, but I would appreciate any offered.
