Hi, firstly, I searched for this problem, and could not find a sollution, so here is my post. I have an Acer Aspire 1524WLMi laptop, it has a GeForce FX Go5700. It has an S-Video port, which I use to connect to the downstairs TV when I want to watch a movie on a big screen (I also use line out for audio which is irrelevant here). Watching a video is fine on the laptop, until I decide to use overlay. I found out it's not a problem with decoders, it's the graphics card or it's drivers because both video files (mpg, avi, wmv, whatever) and DVDs cause the problem, it occurs on ANY program using the overlay whether it is windows media player, winamp, or powerdvd, and trying different codecs did not work. It also does not matter whether I use the Clone method or DualView method of using 2 monitors, it must be directly related to the video overlay in the drivers, or the graphics card itself. In a laptop, there is no way of me replacing the card, also I have tried upgrading the drivers, but when I do they tell me there are no nVidia graphics cards found, when they are blatently are. What actually happens is, when I play the video, it appears fine for 3 seconds, then on the laptop screen, the computer just appers to hang greatly, as if someone stupidly put some cpu demanding process on realtime priority. On the TV, it's just totaly green. I can still hear sound, but it lags greatly due to the software playing the video or DVD is stuck taking 100% cpu usage. Even mouse movement lags! If I manage to move that laggy mouse to the stop button and stop the video playing, the computer resumes it's proper speed out of a hang status, but the TV remains green until I close the video player. A workaround opposed to a sollution is to continuously switch between PAL and NTSC TV output modes (luckily the TV is modern enough to support both), between playing each video, then the video plays fine until I open a different one, but changing the output format all the time is not something I should have to do. Any help would be much appriciated, Acer support didn't help much -- they just said "Use the recovery disk for a fresh install blah blah...." Thanks.
