Hi all, I picked up a DYNEX mini-DVI to video adaptor for my Macbook (white). I hooked it up to my SONY CRT TV (27 inch Wega) using an S-Video cable. Though I had some minor sync problems, I managed to get a stable picture by trying out various interlaced resolutions and I think I settled on 700x??? resolution. Then I set it up as NOT mirrored and moved my firefox window (after reducing its size) to the TV screen. Problem: I am able to view streaming video in firefox in the TV screen. I am also able to go full-screen. It actually looks great! BUT, I noticed that my macbook locked up after few minutes of use. It should be noted that video continued to play and I was also getting sound. But the keys and touchpad stopped responding! When I hit the power button, the window to shutdown the system comes up but does not respond to the return key. I am also not able to switch between applications using Command+TAB. I am able to shutdown the system by holding down the power button for about 4 seconds. Did anyone else experience this problem? Any thoughts/suggestions?
